App closes when pressing the back button

[mesarth]

When I press my phone's back button in a folder or a settings window, the app closes. However, it should return to the previous screen.

OnePlus 5 with Android 8.1.0 (I tested this problem on other phones and could not reproduce it).
I don't know if any other phones or apps have this problem as well, but BitWarden is the only app where I experience this. Maybe the issue is somehow related to Xamarin?

I am not sure why. I can use either button on my Nexus 5X on Android 8.1. Can you try the latest beta on play store?

This was on the latest beta. I don't know why but the problem has resolved after a reinstallation! I will update you if it happens again.
