The new update i installed this morning Nov 18 2020 has caused Minecraft on my Android device to become extremely glitchy.
When opening chests, it takes a few seconds for the inventory screen to materialize, and when you close them they remain open for about 3 seconds. When breaking blocks of any type it takes the game a few seconds to register that the blocks have been broken, even though you are able to move around immediately after breaking it. Sometimes the blocks or items you break disappear for a few seconds before you pick them up. Also there is a lag when you attempt to pick up items.
The Game also freezes during normal play.
