I recently discovered my Pad Air 2 (since a month ago) and iPhone 6S (since mid Nov) are not updating to iCloud when I plug them in to the charger. Both are running the latest public iOS 10 software. I've done the following to no avail on both devices: - logged out/back in to iCloud - deleted previous backups - plugged in, then locked - locked, then plugged I can update manually over wifi when I hit "backup now". My devices are connected to working wifi, backup is turned on, and space isn't an issue. Any ideas?
