After I got this update mobile Minecraft has been bad. Delayed stuff after braking blocks, water doesn't flow like it used to, and auto jump isn't working. Just isn't fun anymore

I was playing one day and then I closed the app and downloaded the update. After the update Minecraft hasn't been the same. Delayed reactions in the game, water hasn't been flowing right, and for some reason auto jump is always on. The game isn't fun anymore please fix it, I had so much fun before the update.
