Controllers doesn't work on mobile anymore, buttons don't function except for B it works as a "back" button not "B" itself.
People find touch screen controls complicated and hard to use so the only way they play Minecraft is with their controller so i hope you fix this bug soon because it makes the game unplayable for some, it's been in the game since 1.19.60
