Hello All, I have the problem, that in iOS 10.1.1 on the iPad, since this upgrade, Acrobat has a hidden side bar on the right hand side of the screen and I always open Acrobat inadvertently no matter where I am, on the home screen or in an app. How can I permanently disable this? I have not found an answer on the Internet. Sorry if I am inept... Thank you in advance for any tips you can give me.
