I went into my settings on my I pad and I selected to upgrade: software for the new version to fix bugs, etc. Now I get a message that says" Cannot back up; This Ipad cannot back up to icloud without verfied email address. two choices: later and Settings. I try to click on settings and nothing happens. I then tried clicking on Later and nothing happens. I've tried turning the Ipad off and restarting, nothing happens. At the top of the screen, it keeps trying to verify but it never verifies. Help!!!
