Here's my problem:

Ever since I've updated to 1.16, whenever I'm in a world and I want to save and quit (this is on my android tablet by the way) I press on the pause button like all normal people do and the loading bar comes up. The thing is, it never disappears. I can still move around in the background but I can't break or place blocks or interact with anything. This makes it so that I can't properly exit the world except for if I choose to close Minecraft which doesn't guarantee my world saving. I haven't been playing for the past week because of this problem, and its only a problem on my tablet which is the device I use to play Minecraft the most. I would love this fix if you can do it. Thanks.
