When playing Android on LineageOS with a Pro Controller (Nintendo Switch 1), attempting to hold the trigger to either place or break blocks only functions if the joysticks aren't currently being moved.
For example, if either joystick is being actively moved and you hold down the right trigger, your character punches the block once, but doesn't continue mining it. If you leave the sticks alone and hold the trigger, your character will begin mining as normal, but as soon as you attempt to move yourself or the camera, your character immediately stops mining.
This issue makes the game basically impossible to play.
Oops, typo at the start. Meant to correct to “When playing Minecraft on Android (LineageOS)”
