The Kindle app is not functioning correctly after the latest iOS update
I am using an iPad generation 6, with latest update of OS. The Kindle app is not functioning correctly: if I tap the top of the screen with a book on the screen, the menu is not accessed as it should be, so navigation, opening & closing, and other essential actions are impossible. Any ideas on how to solve? Thank you in advance for your help!
