This is a question with symptoms limited to iOS mobile devices.
While playing on Landscape Right (home button right side) screen, after watching Google AdMob rewarded ad, the screen always becomes Landscape Left (home button left). That is, the screen is turned upside down. Certainly, we set Landscape Left as the basis in Preferred landscape Orientation, but after seeing the advertisement, it ignores the current slope and it becomes the initial value.
What can I do to prevent this? We use the plugin Universal Mobile Ads to display ads.
