iPhone won't associate with iTunes
I had to do a complete erase and reset on my iPhone 6 which I then restored from a backup. Since I have done that, the phone will sync with iTunes either via the cable or using wi-fi but Apps won't sync. When I've looked at my account on iTunes, my iPhone is no longer associated with my iTunes account. It only shows my Mac and my iPad.
The iPhone works correctly though, I can use handoff, my apps all sync between them like the calendar, notes, etc., the only issue I have is that Apps won't automatically sync between the iPhone and iTunes.
Does anybody know how I can re-associate my iPhone with my iTunes account again?
Thanks.
iPhone 6, iOS 8, 64GB
