I have iOS 9 Beta 5 on my iPad Air 2 and I am not able to update either to the GM or iOS 9.1 Beta. Whenever I click "update" in the setting app, the app crashes. I did a hard reset, deleted and reinstalled the profile, and even tried to update through iTunes. iTunes says it is up to date. I tried to Restore my iPad through iTunes as well and iTunes tells me "the requested resource was not found. Any recommendations would be much appreciated.
