Hello,
Since version 1.21.72 I have been unable to play Minecraft because my iPad starts to get very hot and its battery is dropping visibly (50% in 30m). This heating and battery problem even occurs in the title screen of the game and not just in a world. Before I could play for several hours in a row, but now I can't for some reason.
I'm using a 5th generation iPad Air with the M1 chip and iPadOS 18.4.1
