With the added compatibility of keyboard and mouse controls for mobile in 1.19.10, I decided to try it. The keyboard works fine and most of the mouse works fine, however there is no cursor. I can move my player and click and everything but when I open my inventory there isnt a cursor to use in it. I checked reddit and noticed others having the same problem. This just seems like a minor bug that needs to be fixed. I am using version 1.9.31 so this has been a problem for a while.
