Unloaded and inaccessible chunks appearing in Bedrock Realm

Looks very similar to my issue, only started appearing after the update to 1.9.0. Maybe related? https://bugs.mojang.com/browse/MCPE-41928

To add onto this, if you disconnect while inside the unloaded/invisible chunks, you get stuck on "building terrain" if you reconnect. Very frustrating bug.

You do the most recent backup then join after your realms restarts. A realm restart will fix the chunk issue, mojang should add a restart button to the realms management menu.

Thanks for your patience while we work on this issue - just so you know, you can restart the Realm by closing and reopening it. Go to Subscription>Close Realm>Open Realm.

We had this happening in February and then it seemed to resolve itself.  But this past week we had to restart the realm multiple times a day!  Lost chunks in the nether and overworld, people stuck on loading screens.  It is NO fun.   The realm is 450mb and less then a month old.  Has 50 members.  Cheats are off. 

I was stuck on “Building terrain” while loading in for close to an hour. This was after closing and restarting the game multiple times and rebooting my PC.

• Logging off the realm in or near these chunks prevents rejoining, but is on "building terrain" this means that the following method will not work:

• A realm can be forced to restart if no one is online for 15ish minutes.

• This is because when a player is stuck on "building terrain", the realm registers them as online, therefore preventing the realm from player-restarting

• If this is the case, the realm can only be restarted by the owner

As previously stated, restarts are the only way to fix the broken chunks. Very occasionally, it can be fixed by leaving the area and returning, but this doesn't always work

This bug is somewhere between really annoying and critical. Really annoying when you have to go around said chunks to reach your place and critical if you wanted to do something in the effected chunks or if you try to load in while being in those chunks. The game will just hang in at Building terrain and the only thing you can do is to force-quit the game if you want to play again. That also seems to be platform independent. I see it on Nintendo Switch and on iOS.

We are also having this issue (again)... We had it earlier this year, but as reported, it seemed to fix itself. Now it is back again, and it is the exact same chunk which did not work before and people keep getting stuck (as reported by everyone above). I agree with Nicolas, "the bug is somewhere between really annoying and critical!"

We are tracking this issue in #2037

This is not #2037 and this is not a issue that relates to #2037 as users dont die in unloaded chunks when joining.

Also if this was a duplicate. It would be not as this issue was reported wayyy before #2037. So #2037 would be the duplicate.

Please update the description of this issue to more clearly describe your issue. This helps the devs understand the issue quickly.

Set up a Windows 10 Server and things were going fine until we opened a nether portal. Exiting the Nether is a real problem, sometimes hanging forever at 'generating terrain' and other times getting past that just to find a world with invisible/missing chunks. Running bedrock server 1.14.30.2. Workarounds found so far are only exiting/re-entering the game altogether, or changing the client's render distance to a minimum, walking away from the invisible chunk for long enough for it to despawn, then changing the render distance back. Neither of these are really viable for normal play. 

And out of the blue, it is back. Some areas just don't load in on our realm. And what is funny is, that some players can see all the blocks and for other's it is just gone. I actually fell into a chunk, but could not place blocks to get out. When i tried placing blocks, the blocks that were there  re-appeared: one by one. Other players int he realm is not as fortunate, with whole chunks not loading. It is not just momentary glitches, it either requires a whole realm reset, or an xbox hard reset... simply closing and re-opening the game does not work either.

I have now seen a missing chunk after returning from the nether in a minecraft realms world. No delays exiting the nether in Realms though.

Effects the Bedrock dedicated server as well, when going between nether and the overworld. Reconnecting to the server fixes the issue though.

i've got something like this, but i can even download the realm world and the chunks are still missing,
