The buttons at bottom of the screen (e.g. Fight/reroll/auto-play/level/edit-team) can’t be tapped, I can get them to work only just by tapping slightly above the button. I think it’s the entire section at the bottom of the screen where the buttons are that isn’t registering taps/touches but can’t be sure (e.g. Tapping on the lower half of the menu icons in home/map/quest screens doesn’t seem to register).
I can reproduce this when I change navigation button bar to the (relatively new) navigation bar swipe gesture controls. It doesn’t happen for me if I change back to the (default) 3-button bar. It might also be related to screen size changes, popup view or split screen view that I regularly have e&p open in.
