So I have a complete app and noticed this today. The App has a Navbar at the top and a Tabbar on the bottom. Sometimes the app displays Ads via Google AdMob and sometimes it doesn’t, depending on the settings. I have to similar problems which seem related and might have the same cause:
With ads disabled:
When switching to another app in which the keyboard is enabled and then switching back via the multitask featue on iOS the tabbar jumps up to the middle of the screen and the navbar jumps up behind the status bar.
Rotating the device to landscape and back repositions the navbar and fixes the problem.
With ads enabled:
When switching to another app in which the keyboard is enabled and then switching back via the multitask featue on iOS only the navbar jumps up behind the status bar and the advertisement banner on top.
Pulling up the control center somehow repositions the navbar and fixes the problem.
On android non of this happens. The problem seems to be related to the keyboard but putting keyboard.disableScroll(true); in my app didn’t fix the problem. I also have another view for feedback which pushes an email modal on top of the application. Upon dismissing the modal the same error happens.
I attached some screen recordings of the problem and you can also download the App here to reproduce https://itunes.apple.com/de/app/mein-baseball-club/id1292365213?mt=8
