Lags in version 1.16.101.01

Hi! Installed the release version of Minecraft PE 1.16.101.01 - terrible lags; lags with the extraction of stone / earth and other, the blocks simply do not have time to break and simply disappear, because of this it becomes invisible; a bug with a creeper, when it explodes, it does not immediately break blocks around it; bugs with mobs when they just stand still and do not receive damage; a bug with spawning mobs, a lot of them appear in one place.

But the most important thing is that on version 1.16.40.02 with the included "cool graphics" on my phone Xiaomi Redmi 4x 2/16 GB does not lag at all!
