I'm having a bit of trouble with my iPhone 6S with iCloud backups. iPad Air 2 seems to work just fine. I got a message on the phone that my iPhone hasn't been backed up for 7 weeks so I goto manually back it up and get the message "The last backup could not be completed". I googled the issue and tried everything I read online. First thing I did was a quick reset which didn't work. I already tried waiting it out several days in case it was just a server issue. Then I tried deleting the old backup and trying again. Didn't work. Then I tried signing out of iCloud and back in, didn't work and is a massive headache. I lost all my iCloud photos (they are restoring now) and cards in ApplePay needed to be reactivated. I would not recommend doing that unless you absolutely have too. Then I tried reseting network settings, didn't work and again massive headache. Lost all my wifi and bluetooth information not just on my iPhone but every device (including my iMac) tied to my AppleID. I will be regretting that for a long time. The only other step I can think of is to restore as new. But if getting a back up to work requires me not using a back up and starting fresh then what is the point of a back up in the first place? Has anyone run into this, have an suggestions? Any help is greatly appreciated!
