Perhaps the button is hard to tap for some reason (we've had issues where the tappable area would be too small but no one complained since we've fixed that) but it should allow you to close the mode.
Can you please try tapping on it again but don't pull down as you tap? Just tap?
Hmm, that is very interesting!
Is it possible that your screen is broken? Do you use some protective film on your display/do you use a case?
Please let me know if you'd prefer continuing this discussion over e-mail or on the forums :)
I am having this same issue. I cannot get out of reconcile mode unless I kill the app. The area to tap the arrow is soo super tiny
that even my stylus wont work to get the menu to pop up. It just scrolls the screen down.
