Super annoying bug on iOS 10

This is one of my most frequently used apps. I use it dozens of times a day. Which makes the recent screen rotation bug all the more annoying. The app will randomly launch in landscape or portrait mode, irrespective of the actual orientation of the phone. Restarting the app, restarting the phone, reinstalling the app all dont fix the issue.
Aside from that major flaw its excellent. Fast and stable. Too bad its up to chance if it launches in a usable orientation.
