Two weeks ago I bought an iPhone 6s and I restored my iCloud backup from my 5s. It went perfect. Today, I returned my 6s and got a 6s Plus. I restored my iCloud backup from my iPhone 6s. It went wrong. My messages (SMS, iMessage), recent phone calls, all the content from Health and more. I have tried restoring several times from several different backups, but it's always the same. I don't know what to do. I don't have an iTunes backup because I relied on iCloud (as I said, it went great when going from the 5s to the 6s). I'm using iOS 9.1 on my new 6s Plus and I was using iOS 9.1 on the 6s I returned. It's a bug from iCloud? A bug from iOS? Any ideas on what to do? Thank you very much.
