Since the 1.16 update, Realms has exhibited lag that becomes so bad as to make the game practically unplayable. The problem appears to become worse as additional players join.
Symptoms include:
Mine carts on powered rails slow down, their position updating as slowly as once every two seconds. When this happens, the mine cart can be half the speed of a walking player, or worse. The slowdown comes and goes without a repeatable cause. Sometimes leaving the cart and re-entering it can cause or stop the lag. Sometimes crossing a chunk boundary seems to change the amount of lag.
When mining blocks, the "drop" animation may play as many as six times before the item actually registers as dropped and is picked up by the player. When this is occurring, if a column of gravel falls onto track or a torch, the spray of repeating drop animations makes it practically impossible to see.
When placing blocks, especially in rapid succession, blocks may disappear immediately after being placed. (Prior to 1.16, blocks would re-appear after being mined; in 1.16, we instead have the opposite problem of blocks disappearing after being placed.)
Mobs may move in stop motion, their position updating once or twice per second. This also affects the rate at which hits are detected on them: you hit the mob, it takes a second for the hit to register, and in the meantime the game may register one or more hits against you by the mob.
This issue is particularly bad with slimes. After attacking a large slime, there is a pause of one or more seconds before the smaller slimes spawn. See https://www.icloud.com/iclouddrive/0XciVC13vDNCGCQWN6HAtRNQQ#save.
The issue occurs for multiple players in our realm. In my case, I am playing on an Xbox One X connected directly via gigabit Ethernet through business-grade networking hardware over a 300Mbps/30Mbps cable connection. My latency to AWS is 39 ms (US-East Virginia) to 120 ms (US-West Oregon). Other players on our realm are located in two other states. Between us, we use three different ISPs. The issue is independent of networking hardware, ISP, or Xbox One revision.

Note: Problem started with MCPE 1.16, but is equally bad, if not worse, under 1.16.1.

This is also an issue for me, im paying for the realm subscription but i cant even play on it because of all the lag. please fix this issue mojang so we can play what we paid for.

We are getting this issue lately as well, exactly as explained above. Mostly when two or more players are on, but even one player is online this can happen. Seems to be getting worse this week. My internet is 300-500 mb down and 25-30 mb up, so speed of my connection not the issue.

Also experiencing this issue, have excellent fiber internet. Getting server errors additionally and booted from game. Is there a customer service person I can talk to about a refund or extension of our Realms subscription? We're paying for a service we aren't getting.

i am also experiencing this lag issue with my Realm, but it should be noted that other members of my Realm, (on different consoles than XBox), are seeing the same issue.
it's getting to the point that i am investigating other hosting options.

This has gotten horrendous in the last month. On my Xbox we primarily play a world that belongs to my girlfriend, which is not the default profile that loads on start up. It's takes so long just switching profiles, a lot of times crashing, and then once the world is loaded, horrible lag when playing with 3 or even 2 people. Very frustrating

I'm having the same issue on pc after the most recent update (v1.16.100). The realm is basically unplayable for me, but my friend on an original Xbox is not having any issues.

Same issue with Realms Plus on Windows 10 (v1.16.100). Unplayable at times.

agreed since update on 1.16.1 on realm's me and my wife have experience extreme lag while playing together i play on windows and she plays on the Xbox.
we were playing up until the update for a couple weeks during the evening and once the update dropped everything went downhill.
for example villagers freeze up or lie down in bed and start drifting across map while still sleeping other players disappear for long period of time along with a lot of unusual problems. we are not talking about regular place a block and it disappears issues here it some times makes the game unplayable especially when dealing in villages .
just go back to old update or fix asap

Since Bedrock v1.16.100 was released, the lag has gotten much, much worse. I'm now playing on an Xbox Series X.
If you're on the realm by yourself, it's usually fine.
But if there's even one other player...
When riding a minecart, the cart now moves about 4 blocks, then pauses for a quarter second to half a second, and continues this indefinitely. It doesn't get better across chunk boundaries; it's constant. There's constant lag for mob updates. Other players update with a similar hitch, like they're only updating 4 times a second at best. Block drops are similarly slow.
As it stands, Realms is not fit for purpose as a product.

A Realm (bedrock) I play on is now unplayable for me and a few others. Not been able to play since the 1.16.100 update. Having to break blocks multiple times and same with placing. It wasn't too bad before the 1.16.100 update but since that update, I cannot play and nor can some others that play with us.

I am also seeing the realm being very laggy after the 1.16.1 update. Ghost blocks and mobs not animating, minecarts freezing, can't place blocks without relogging. During a raid the mobs didn't visually move, but I was being attacked by them from 50 blocks away.

I've also experienced the slow minecart problem - I got out and overtook it on foot.
I've also had a problem with water flowing really slowly once placed and a really bizarre issue with sleeping villagers flying through walls, out of villages and off into the distance.

We have the same issue and it's noticeable when there's only one person on. Affects minecarts and all mobs. Sometimes the horse you're riding or other critters on a lead will stop moving for you completely, although other players might be able to still see them behaving normally. Usually closing the game will reset frozen mobs but the general lag remains.
Have had a few invisible creeper issues due to this, can't even tell that they're there until it's too late.

this is getting worse every update. They need to fix this i spent 80 dollars and this is what we get? Wow. Now it has an error where you need to join 2-3 times to join it

I've been having major lag issues in my realm since at least early November. I always have block lag, and my members tell me that all sorts of random weird things happen to them. Its made this whole last month a pain..

Same problems. Even deleted the pending tick data and that didn't help.

I've had the very same issues. I have to break most blocks multiple times and mobs don't move.

The problem is improved in 1.16.200 on Xbox, but still exists. With the game running from the internal SSD of an Xbox Series X, over a stable 300Mbps connection, travel in a minecart still "hitches" every two to five blocks. The pause is now momentary instead of one second or more, but it's still nowhere near as smooth as earlier versions (which themselves were prone to hitches). The problem still appears to scale depending on the number of players in the Realm.

I've played on my realms for 2 months and it stayed fine but recently is has had immense lag even with two or three players on it at a time. I have never had the full 10 players on but we were planning on doing the ender dragon fight and I hope this issue gets fixed before that because at this rate, I don't think realms can handle 10 people even though it should.
In a typical Java Server, having more people on does make it laggier and even if you can hit capacity of the server, doesn't mean you should since people will be very laggy. But because this server is hosted directly from Minecraft Bedrock so the full capacity of 10 people is what I should be able to play!

exact same issue im on google fiber internet and i still lag really bad. we just had a raid and it was a joke because even creature couldn't move fast.

Here is an example of the mob movement lag I see:
[media]
Yeah I have what Jim Craft is experiencing. It's not as much as him on my realm, but I do experience times where it's unbearable.

Having this problem on my Realm with 4 players on and it didn't start until 1.16. Same as the Jim Craft video.

i put a video showing realm lag during 1.14 this stuff was going on even before 1.16

I started a realm that has about 8 players on at a time. the longer that we play on it the more and more laggy everything becomes. If anyone has solved this issue, please let me know

Recently I have run into the problem as well. It has always been around, but lately it is really bad.
I can take up to 5 times to attempt to eat a food before it actually counts as being eaten. Redstone ticks extremely slowly, and so my contraptions take ages to actually activate. Mobs move in increments instead of steadily flowing. Water slowly and unevenly pushes players or mobs that are flowing in it.
I do not know what is wrong. Everyone on my realm experiences some parts of this (some worse than others). Hopefully this problem is fixed soon!

Edit: The same issue happens to me & my friends on bedrock. Food takes 4 tries to work with potions taking up to 10, and mining blocks sometimes completely cancells out and places them again. Water can take multiple seconds to move 1 block and striders move like minecarts stopping every few seconds, and then teleporting you multiple seconds ahead. Also villagers have trouble choosing new workstations and it makes it very difficult to work with. This issue happens on ps5, xbox series X, series S, ps4, xbox one S, xbox one X, and probably more. Issue either gets worse at time goes, or it gets worse because of more entities. Chunks do not load properly when using your elytra which creates you flying into an invisible barrier and being able to see under the ocean and under the ground. Elytra deploy is delayed and very laggy. Last thing is when shooting a bow it can shoot the arrow multiple seconds late, or not shoot the arrow at all. Me & my 8 friends will not be renewing realms until this issue is fixed for it is nearly unplayable and we'd have more fun playing other games.

Same issue here on xbox one x, I'm the realm owner and it seems I have the worst of it.
Before update I had some lag, but not nearly as bad.
NAT type open, xbox speed test shows 100Mb / 20Mb, other things on xbox work good.

I hate the be this one person but this issue has been out for 7 months and we haven't had a single mod actually talk to us about what is happening to the realms. Please if any mod sees this comment, respond with anything and if you can, send out an eta of when this will be fixed.

I had this problem before when playing on my friend's realm using Windows 10 Edition, the game would run great FPS-wise but the tick speed was so slow, mobs would move weirdly and food took multiple attempts to actually eat. However, I found out that my PC's wireless network adapter was the issue. By default it was set to 802.11B, which is the slowest option. I changed the settings to a faster one, and ever since I did that, online play has been running almost flawlessly! This is just the fix that worked for me, but hopefully it will also be able to help other PC users.

Just started playing on Bedrock, leaving Java Realms behind. Got a realm going here with a handful of friends. As soon as the world size breached 100Mb, the in-game lag seems to have gotten crazy, unplayable almost. I don't know if it's correllated to the world size, or to the game version, or even just the fact that it's Bedrock Realms, but this was never an issue over on Java realms, not like this. 😞
This is seriously bad, like not worth the monthly price in its current state-bad. Any information I can provide to help track down the root of the issue, let me know and I will. I want this to work better.

I have the same issue for me in my creativ world if my renderdistance it high it lages massifly if i look at a single leave (i have a texturepack that changes leaves a litle bit) it just lagges if no leave is on my screen i have super smooth gameplay even with verry high renderdistance

I am having the same issues with my realm, particularly when mining in the nether, I get lag spikes and a whole row of netherrack that I just mined will reappear sometimes blocking me in from behind.

Please fix this. It's disgusting that you can offer your customers a paid service that hardly works. And then you won't even update it properly to meet the needs of the game and it's players. There may not be many people capable of doing it, but SOMETHING needs to be done. At the very least, you should give the player base an explanation...

playing on pc and my game runs perfectly fine except for massive input delay where i cant start/stop moving when i want to and it has killed me multiple times. happens sometimes in singleplayer but its atrocious in realms

I have the same problem but also when you teleport people to a high place or a low place it registers it as falling and they die from fall damage.

this is definitely a realms issue, i was having these same issues and I put it on a dedicated bedrock server tonight running windows and it works so much better without problems, no lag at all. Maybe theyre not giving realms customers enough resources to properly run their games because it's not the version of minecraft it's realms

I have the exact issue with realms the lag is ridiculous, I tend to eat the same time 5 times and the block lag is a nightmare you have to be careful when mining that your block dosnt come back and you suffocate

Yes please fix this. I'm a very active realms player and I own my own server and realms are always really laggy. They can barely handle more than 2 players. Realms are terrible and i wish they werent.

This really needs to be fixed, I'm a member and help develop a realm. We get around 3 people online and after that we can't really do anything consistently because of the lag. Please, please, please fix this.

Is there a way to get notifications from a report because this is exactly what is happening to my realm and is making it so unplayable.

The easiest way is to "watch" it and then emails will be sent to your linked email.
There might be other ways but that is the way I use!

Having similar issues with just 2 players on the realm. This is especially noticeable with the elytra, chunks fail to render and you can see through the surface. The random deaths while using elytra because I flew into an unloaded mountain is extremely frustrating. It is getting to the point of unusable.

This did just happen to me. To me, it was relatively unplayable until later, when the lag mostly subsided. 5 people were online last night and we had lag issues we had never had with 6 online. I cannot confirm lag when flying with elytra, since I did that with 5 people on without lag.

Yeah, it's a very unenjoyable experience to play on my realm right now. The lag is there with just one person, but it goes insane with two or more players. Should be fixed ASAP.

Just chiming in to say, same here. Xbox One, two players, one wired, one wireless. Weirdly the wired connection seems laggier, but that may be because I was traveling via powered rail, so it might have just been more noticeable.

The problem is even worse on 1.16.210.
With 1.16.200, the severity of the issue seemed to vary from day to day. Occasionally, logging out of the realm and then reconnecting a few minutes later (such as after a bathroom break) would improve the problem. Sometimes the improvement was brief, sometimes it was long-lasting.

Same, ive had the issue in the past, and it came back, i literally changed isps thinking it was that... given i had issues with other games but i literally have fiber and my ping to aws is 16ms and im hard wired so i know its not my wifi

This became more noticeable in latest update 1.16.210. Tested everything, only happens on realms. Trying to fly with elytras with fireworks from the ground is nearly impossible, even replanting crops by holding right click skips several blocks.

Really need to vote for this. Yesterday when I bought it, It wouldn't upload my world, today the lag has been worse. The server is really appalling.

This really is pretty bad. I just started a brand new realm with nothing built in it yet, and with nobody on just waking through a village was giving some pretty massive frame drops. This is on an i7 CPU with a 2080 graphics card, and it doesn't even feel playable.

Having all of these same issues too after update on Realm . 1.16.210 is not playable. Our Realm is useless. Mojang should be giving refunds to people with realms with how bad it is.

I havent been able to update my realm, delete or replace it since the update

We also have the lag problem since the last update it is very hard to play, we play with 4 players on realm plus on ps4.
please fix this problem

Well, thank you for the massive problems both for me and the kids. We are super faster internet and cannot even connect to realms.
MC has turned really bad and is not even playable anymore. Now I have angry kids that are upset that we cannot play together.
Hire a new development team. This is just insane. I have 2 reals and cannot access any of them on my 12 Pro Max phone.

Been having this happen with our Realm as well. Mostly player count-based. We have 1-3 players on with a mix of PC, PlayStation, Switch the Realm is alright. Start getting to 6-8 players and things become unplayable. Enough so were looking at what it takes to host our own. Please take a look at this.

You can't play with these Lags. Blocks reappear when mined. Dropped Items lagg their way down. mobs, horses, Elytra and minecarts move in slow motion. Switching between dimensions causes even more lag. Big servers with 30k players get their servers running perfect and you don't even success at creating a 10 player realm that works fine. I pay for the realm every month and so do thousands of players and you accept these circumstances? I want the server-environment that I pay for. This is just unplayable bullshit

We are using a realm on Bedrock and are now starting to experience the lag as well. There are 4 of us on a 10 player server and it lags if there are more than 2 people on at the same time. I notice the server ticks are slower and things such as opening an elytra are near impossible.
It seems to get worse based on the number of changes made to a chunk or chunks nearby. Even the nether is laggy after we cleared out ready for making a nether hub, though nothing has been built there yet. This is with all players on, but in the nether so the realm doesn't need to be loading both dimensions.
We've tried it on peaceful as well to see if excess mobs could be a problem but the issue persists.
All 4 players are on PS4.

I went ahead and cancel my realm for now since it’s un-playable. It’s sad to see them not take this issue serious. I payed for a usable product not a broken one. Won’t go back until it’s fixed if that. I went and started own server for now with no issues. I really hope they fix it.

I've now canceled my Realm Subscription since the game is borderline unplayable. I've just downloaded my world and now if my friends want to play, they just have to boot up and play from my box when I'm online. I can't believe they haven't responded or fixed this yet.

Yea. Its getting worse everyday. Instead of fixing it. They add marketplace stuff into it. Its sad because in the past realms were smooth. Like im paying money for this. Im never extending my realm membership ever again. And mojang. If you're reading this comment. Please fix your realms. because you will lose alot of memberships.
Did i forget to mention that i put a video of lag here that was 1.14.0???

Yes. this is so sad. We used to have a great time with the kids and reals. We managed to get better performance when we left realms and just used LAN and windows 10 only. But I liked the idea that the kids to play without me joining them. Now we are back to using a single source for the worlds again 😞.

It would be nice if we could at least get some feedback on this. I am paying for 2 realms, The one I play on is nearly impossible to fly with an elytra, and the block lag is extremely frustrating. It looks like I will also have to cancel myu realm and move to locally hosted. I would run a server here at the house, but I play with my kids and one of them only has an xbox. Kinda just screwed all the way around. It's really unfortunate, we love playing.

I am running my own server at home and the Xbox will see it locally. Try it, it’s only outside your home where you have to make changes to your setting on each device. I downloaded my world and it’s all good now.

I am at this moment looking for any viable alternatives to realms. This is horrendous. I will be cancelling my realms subscription within the month if we dont get some kind of feedback or fix.

Agreed - i'm hardwired in and not having issues with anything else and this is how my 10 year old neice and I bond but the lag is horrific. Can't even fly without dying or almost dying.

This is so annoying! I have been watching this issue for over 2 months (my comment is back up there somewhere), and I have NOT seen any mods say anything.
All they do is pop in and say someone else has duplicated the problem, and that they get referenced here. That is just sad.
As I know other people have said, the big servers can run hundreds of people with almost no problem at all, but a small little itsy bitsy realm with a max of 10 people can sometimes barely even run a few? That seems really messed up to me.
I am extremely tired of having to deal with this. At least if some mods can come and say SOMETHING useful, that would be a huge step in the right direction. Referring people here after the problem is duplicated does not help. Correct me if I am wrong, but it shows us that you care less about fixing the problem than grouping everyone together so your list of problems can look nicer.
Watching the number of votes on this issue go higher and higher and higher does not give me any hope that they will fix this issue, and very well may have me cancelling my subscription to realms. Why would I pay for something that the owners could care less about fixing a huge problem with it?? To me...that makes no sense.
Minecraft is an amazing game, I just think it is sad to see this happen to so many people and they do not even directly say anything to us that is really all that helpful. For such a big business platform and hosting shows to give out information about an update...they do not even have a call center. Even smaller places/businesses have a call center, and those are so useful because you can transfer much more data through your voice (and have it be much more meaningful), compared to over text on a screen.
All I want is some mods to take time from fixing tiny little pointless bugs to fixing a huge issue that is ruining the experiences of many! A tiny faulty texture is much less important that a huge lag spike (or even lag session) that ends up killing you via elytra, eating, or drinking, or having minecarts go slower than walking, or standing in unloaded chunks and floating in the void, or having Redstone contraptions fail or take forever to compute due to the low framerate.
These are much more pressing issues...please fix them over stupid little bugs. Or at the very least - ASSIGN SOME PEOPLE TO THE PROBLEM. Maybe it will make stuff actually start to happen...maybe.

There was a time I could have a whole sorting system on a 10 person realm. Not anymore. Now our realm has to make rules about how many mobs you can have and how many hoppers you can have and still a 10 person realm struggles with more than 2 people on, as if it's only allocated the same resources as a 2 person realm.
We all wish we could just set up a server but we have too many console players. C'mon guys, make it so we don't feel left behind when using your own subscription service!

Great... Our bug report got linked to a bug report with 0 feedback from the developers.
I am considering canceling our realm untill the game is playable again.

Just cancelled my realm until this is fixed. Got to love you have to mess around creating servers to get it playable again 😞

I own 2 realms and both have been abandoned because of the lag issues. I am the only one who gets on every now and again to build something on request, because I play on a PC the others are xbox. It is still laggy with just 1 player. We only have 4 players at the most but it isn't fun for them when they get on. It would be nice to get some sort of feedback for this issue so we can see a light at the end of the tunnel. if there is no feedback I will be forced to stop my realms subscription until it is fixed.

Cancelling realms today this is incredibly disappointing. Let's keep commenting to get it prioritized. Such a great game - sorry to see this happen.

Me and my friends, who play on 1 switch, 2 iphones, 1 ipad and 2 pc's colectivelly, experience unbearable lag when 2 or more of any combination of people try to play on the realm. This is a big issue and needs to be fixed.

Many of my issues include: Breaking and Placing Block Lag, Incosistent Nether Portals, Issue with consistency when joining the realm (taking damage when loading in, etc.)

Ok, my family is done with Minecraft.

Okay they haven't even acknowledged this problem with a response. If I wasn't the one paying for the laggy realm I would cancel it instantly. The support from mojang it's incredibly unsatisfactory for a paid service.

To add some additional information: This issue occurs when more than one player logs onto a server (so anytime multiplayer is active), and it applies to Windows 10 Edition as well. Other comments have suggested it applies to Switch and PS4 as well, in addition to the other platform of this post, the Xbox One X. I play Windows 10 Edition on a wired connection with download and upload speeds of 20-30 MBps, or 160+ Mbps. Ping does not exceed 40, usually sits around 30 when I test my connection to various games. If a Mod could update this post to apply to the listed environments it may be more useful (likely this applies to all environments).

We need to put more video proof here so that way we can get mojang to fix this.

The lag on our realm makes it almost unplayable with more than a couple of players online. It is more noticeable on the Nintendo Switch than the PS5 but we still notice some realm lag even on the newer platforms.
There are times when flying with the Elytra that chunks will not load. There are times where blocks are being mined but do not disappear. There are times that you place blocks and nothing shows up. On the switch this is usually followed by never ending loading bars and then the application crashing.
To think we pay for this service and they make it such a hassle to connect to your own hosted server on the bedrock edition.

Okay I have logged on today after yesterday's update and all my lag issues have cleared up. Even though the patch notes mention nothing about this problem, it is fixed for me. I note I have not played for a few days, realm owner updated the world as required with new update and all of a sudden it works. I repeat I did absolutely nothing to fix this myself.

3 Realms for me are extremely lagging/choppy today, also experiencing block generating issues were they are delaying in generating. Over the last 6 months there has been a load of issues for myself and other members and to be quite honest its not acceptable and I'm seriously considering to stop paying each month as its just not good enough, and the silence from Mojang speaks volumes!

I have purchased accumulative of 3 realms now. So far my experience with the first (2019 or so) was by far the best and had minimal problems progressively as I bought the next 2 realms, they have been progressively more laggy to the point now where it is unplayable. Usually the first few days it is fine and works well however, it has bipolar and majority of the time it is horrible. I am not sure if it is due to my location of being in Australia that is the issue, or if everyone is suffering from this issue however the realm has become completely unplayable. I love the idea of realms and I do hope one day it becomes good again.

I have all but givin up playing minecraft as ps4 player and the lack off being able to go to and independent server host

The lag is growing increasingly worse! When 1.17 first released it was as if previously laggy chunks were fixed! But the lag has returned and is becoming increasingly worse and becoming a menace in all areas of the realm! I think we're ready for a fix!

Lag now causing progress losses!
Recreate:
-Spend 10 minutes building something while the heavy lag is present
-Choose 'Save & Quit' from the game menu
-After 2 or 3 minutes, rejoin and see that you have lost progress
Since this lag/lost progress happened on other occasions in the past, it is a recurring problem.

Can confirm that this is a massive issue. A community realm has JUST started today, with a fresh world - day 1, and in less than 12 hours, the lag is unbearable - even solo as the only user online. Not sure what causes this. I mean, player count certainly is an influencer - but is it total player count, or player count online? I’d say the former. But regardless, a paid server shouldn’t be this atrocious. An update on the stability improvements that are supposedly coming to realms should be posted ASAP please.

As a temporary solution, emphasis on temporary, I find that the following command will GREATLY reduce lag - at least on the community realm:
“/kill @e[type=item]” - this will kill all dropped items on the realm. It seems that realms for whatever reason do not eliminate the items from memory even when the chunk is no longer loaded.
Hope this helps you guys.
You can be lazy and put it on a repeating command block with a huge ticking delay if that’s what you want too, but I think it’s better to just do it manually.
This is of course assuming that your realm has cheats on, if it does not, I’m afraid this is not possible.
But I can confirm that item drops are a massive memory hauler.

This issue made me unsubscribe from realms. Please try to get this looked into.

I really wish I'd seen this issue before paying for realms. Does anyone know if this issue affects dedicated servers as well, or just realms?

This is game breaking, I'm playing solo on our realm and I can't do much. Every time an new entity drops from an ore block or just anything really, it lags like crazy. And it's not the device (played on Windows 10, Nintendo Switch AND Android) nor is it my connection (400+ mbps)
I made my friends and I move to Bedrock and Realms because I thought it would be more stable under Microsoft's umbrella... So far, I regret my move and this is completely unplayable. If this doesn't get top priority when people who play realms repeatedly pay a subscription, I think it mean you care little about your customers. This has been going for too long now.

We found that the unplayable lag went away almost completely after we all stopped playing on the realm completely for 2-4 weeks. The realm worked without any undue lag, regardless of player load, for a few months thereafter (right up until 1.17.30, which broke Realms in so many other ways as well).
Since the problem persisted across server version upgrades, I don't think the issue was due to a memory leak / long uptime for the server instance. If so, I would've expected improvement after a server version upgrade.
It makes me wonder if the issue is related to specific server hardware instances; possibly, discontinuing use of the realm for several weeks causes it to be stopped and later migrated to another server when accessed again? That sort of thing happens with cloud services, and would explain the results we saw.
Under 1.17.3x, we're seeing some lag, but not as bad as when I originally reported this. Occasionally, block drops are delayed. This is particularly noticeable when mining deepslate coal; when doing so, blocks frequently disappear and then reappear instantly. Travel by minecart is generally smooth, with only minor "hitches" that are barely noticeable. (Before our break, minecart travel would routinely pause for half a second or more every few seconds, frequently resulting in minecart travel being slower than walking speed.)

My brother has been having major lag issues and can't even play because anything he does eventually sends him back to the same spot. I had him clear his cache resources and now he can't even join the realm. He is on the PS4.
I did some mining with my family, gathered a bunch of resources then ended up in the spot we were at before we headed out and lost 30 min worth of playing and collecting.
I have not had that happen since and thought maybe it was due to the realm trying to save, which fails and auto restores the last backup? But that doesn't account for when I was watching my brother glitch out and mine seemed fine.
Very frustrating for paying realm users and hope it gets resolved soon.
