Every world, regardless of what's in it, has a weird lagging issue. Players move fine. But all other entities move extremely slow. Redstone is very slow. Command blicks have a delay. Even if I create a new flat world, and place nothing on it, this still happens. I am on Minecraft Bedrock Beta 1.14.2.51 (latest beta release), using a Samsung Galaxy S8 running Android 9.

This is now occuring on my Xbox One.
