Back button issue (bug), inconsistent, only top part of screen shown
After using the in app back button I see only the top part of the screen of "Songbook".
I have this issue on my S2 TAB in portrait mode. Once I turn my screen to landscape and back again, I have full screen again.
If I use the TAB back button, I am thrown back to "Your collections" after it flashes past the "Songbook" screen. In this case I have full screen.
If I start in landscape mode, the action of in app and TAB back button remains different, however in app now maintains full screen.
