Then the auto exploration and auto fighting buttons are bugged. The battles don't continue on their own (except for the battles with just one enemy) as you are always asked "Battle foes", "Collect coins", "Battle elite" and so on.
Something buggy though. I've tried that button already and it didn't work. (Now I've tried it again and it works)
Not sure what's causing it or what prevents it from working.
Anyway: Now that I know that it CAN work, the game is far more fun than before.
Another bug I found: I have an item "Nature Warrior of Thunder", which simply locks the game after one battle. The next battle is visible, but the game does not react to inputs. I can't even change UI screens then.
