I'm having trouble with back button functionality. If user presses it shortly I execute command (through blueprints) 'vr.oculus.ShowQuitMenu', otherwise it is handled by oculus SDK to display global menu and it works fine in development, but when I prepare the app for distribution and send it to review process I get back that the app is crashing when back is pressed.
Has anyone encountered such isssue?
I've read that it was the case in earlier versions of the engine because JNI was detaching, but it was fixed, but maybe there's also a place where this is happening?
I'm using binary distribution of UE4 4.19.2 and testing the development build on Samsung Galaxy S7.
