I plugged in my keyboard and mouse to play Minecraft on my phone and everything worked completely fine, except there is no mouse cursor. The main menu doesn't have it so I have to use the arrow keys. There's nothing in the inventory so I can't even manage items so playing things like sky wars are just not possible. I tried using assistive touch, but it acts like your finger so it doesn't work properly and isn't even close to a solution. I've searched everywhere and tried everything to fix it and nothing works. It seems it's just a problem that needs to fixed in the next bug fix update.
