Not sure this is a bug exactly, but I am using a Google Pixel 2, and when I accidentally press the back button, and the "(press again to confirm)” appears, it covers the folder selection button in the top left.
There doesn’t appear to be a way to swipe the notification out of the way once it appears, which forces me to wait 2-3 seconds if I need to switch to another note.
I normally just swipe directly on the screen to pull up the list again, but it also covers up the top item in the list while on screen.
Perhaps the Exit Confirmation could be centered, or made so I can swipe it away?
