It was a resourcepack. I'm sorry. How do I erase this report?

The same happens to me, I found a solution that is not at all pleasant and it is all the worlds files and resource packages to pass them to a place where you know that they will not be deleted after (in my case) I do that. 

I have this issue as well.  The problem is not that the items fall on the floor, it's that the cake itself is not crafted, even after the items are consumed.  Keeping one extra empty bucket in the inventory does not help.

This is the same glitch I get when trying to craft honey blocks.

I have the same issue.  I'm running bedrock edition v1.4.3 on an iPad Air 2. The dragon's health bar first appears when I enter the end, but disappears about 5 seconds later.  The dragon freezes in place, and the return portal is active with the egg on top.  I cannot interact with the dragon, but I can interact with the egg.  If I exit the game and then re-enter it, the dragon itself disappears.  I've not activated any cheats or codes at all in this world.  This bug occurs regardless of set difficulty level.  I've attached a screenshot.  I'm running the natural texture pack.

Ah, I have different versions on my devices. This one IS running 1.2.3!

Yes, there are no caves that aren't filled with water. The mobs are definitely spawning directly on the glass. I have also made a huge area made-up of bottom slabs. The endermen do NOT spawn there ... they will teleport there only after spawning on the glass blocks. Usually the endermen spawn only one at a time, but I have seen up to 4 spawn simultaneously on the same glass block, only to spread out or teleport to slabs after spawning.

I don't think this issue is fixed. Endermen still spawn on the main island of the End (where the dragon spawns), even if the ENTIRE surface is covered with water. They spawn on glass blocks and on top of the bedrock regardless of light level. They do not spawn on bottom-placed slabs. I have reported it.

This affects iOS as well. I have an iPad Air 2. It's impossible to keep tamed parrots alive because of this glitch. I also agree that their distance for mimicking noises is too far - especially zombie sounds. The constant noise is annoying, and with so many underground caves around, it really isn't very helpful.

This also affects iOS. I have an iPad Air 2.

Yes! My kids and I have bought several of the mash-up packs and community worlds. All of them are locked, unless the device is logged into the xbox account it was originally purchased with. My kids each have child xbox accounts and I have an adult one. I have purchased packs and worlds while logged into my xbox account, and I have also purchased some packs and worlds while on my kids' devices - and not logged into any xbox account at the time. We have always been able to "restore purchases" in order to use content I've bought on our various devices – until now.
The marketplace wants me to re-purchase all of the packs so each of us can access the content I already paid for. It's crazy to expect me to pay 4 times so me and my kids can access the content on each of our devices..

I also have item frames drop off the wall. My world is not very big (80 MB). I only get item frames dropping (and subsequently despawning if I don't realize it in time) in two of my rooms. The first is my chest/storage room in a small basement of a building containing a small forge (hoppers and chests connected to a single furnace). The item frames (and the item inside the frame) will drop and float on the floor, but only off of one of my walls. The wall perpendicular to it is not affected. The other room Ive had it happen is just a small room in my house - no equipment or machinery there. The item frame will drop off that wall too.
Both rooms/walls affected are only east/west facing. I've attached a picture of the room where it commonly happens. Only the one wall on the right side ever drops item frames.
Oh, and I'm not on android. I'm on IOS – iPad Air.

This also happens when naming tamed wolves.

All of my family's mash-up packs and community worlds are now locked since the content is linked to the xbox account. Content bought on my account is locked for my kids. Content bought on my kids' child xbox account are locked for each other and for me. I can't be expected to purchase each pack 4 separate times so me and my kids can all use it!

Yes. All the packs and worlds my family have bought are now locked all all of our devices, unless I'm logged into the xbox account that the purchase was made under. My kids can't access content I bought under my account and I can't access content I originally bought on my kids' devices.

My family also has this problem. I have an adult xbox account and my kids have child xbox accounts. Now we can only access the content we've purchased (mash-ups, community worlds, etc.) if we are logged in under the specific xbox account they were purchased under. You can't expect me to purchase the same content 4 times in order for me and my kids to all play it!

This problem shows up in mine with the natural texture pack.

Sunflowers are also super buggy - the textures don't even line up correctly. Newly planted pumpkins and watermelons don't even show up at all. Several different items don't change sizes when they are put in an item frame – red and brown mushrooms do this, so do ladders. There are probably more. Lllamas and beds don't have a texture - if I have another texture pack layered beneath this one, that texture pack shows through on the llamas and beds.
Unripe cocoa beans also look weirdly flat. They are invisible in the normal texture, but look flat in city and natural pack.
