My wife and I both upgraded to the X and restored from an iTunes backup. I keep iCloud backup on all the time and then periodically turn it off to perform an iTunes backup. Whenever we switch to a new phone I perform an encrypted backup and then restore from that. Since we have restored on 11/3 iCloud has not been able to complete a backup. We had this issue a while back and an OS update seemed to fix it. Anyone else having the issue? TLDR; iCloud backup is not working with our new phones.
