Undo iOS update
I recently updated my iPad Air2 to iOS 14.6, and when I attempted to open an older app, I got a message that the app needed updating. I have been unable to get the app updated; therefore, I need to undo the iOS update to get info from the app that I created within it. I will then redo the iOS update to 14.6. How can I do this, safely?
