Q: Error -23 when updating to iOS 9 via iTunes
TRied to update my iPad, iPhone and iPod touch through iTunes as they all failed to update wirelessly. iTunes hasn't helped but it has told me that I have error -23 but I have no idea what that is. My main reason to update to iOS 9 was so I could download GuideCentral again as I'm very popular on it. Anyone had this error or may know how to fix it. It's strange how the same thing has happened on all my devices.
iPad Air Wi-Fi, Cellular, iOS 8.4.1, It's a good iPad - won't update tho
