Hi all,
today, I backed up my iPad (Wifi+Cellular for AT&T, aka iPad 3) through iCloud.
Then I restored iOS 9 on it, as per release notes procedure. It took sometimes, but appeard to go well.
After rebooting in iOS 9, it never allowed me to restore from iCloud backup, wether from the iPad itself or from iTunes. In fact, it never offered me to restore at all.
iTunes told me my iPad had never been backed up to iCloud.Going through system prefrences on a Mac, or iCloud prefs on an iOS device also showed a size of 0 for this iPad (similar to what is stated in release notes). On the device itself, though, last backup time was correct.
So... How could I restore ?
Issue was : my iPad was still connected to iTunes... So I disconnected it, erased it one more time, and on reboot, I can now see the correct backup and restore from iCloud (currently underway). OK, I could have known that, but I restored so many times being still connected to iTunes that I could not imagine it would cause an issue, hence my note and warning to the community.
Kudos to Linda, from AppleCare, who supported my stress... Not sure she was even allowed to help me on this case ! 🙂
