iOS 9 beta
I bought a used iPad Air, and every time after I switch on the screen and enter my passcode, I get the following notification. When I go to Settings, it says there are no updates available and that my iPad is up to date. The current iOS version is 9.1, but I know there's a 9.2 because my iPhone has it. What does "please update from the iOS 9 beta" mean?
iPad Air, iOS 9.1
