When playing on iPhone 11 Pro Max (iOS 13.0) with iOS display "zoomed", the touch control is shifted from the original button location, so that I can hardly make the button work, thus makes the game totally unplayable.

FYR
1. It had no problem before iOS 13 on iPhone Xs Max with display zoomed.
2. It also has no problem without iOS display zoomed.

Thanks.
