Error message: There are purchased items on the iPhone “Patches's iPhone (2)” that have not been transferred to your iTunes library. You should transfer these items to your iTunes library before updating this iPhone. Are you sure you want to continue
When trying to download and install new security updates to my iPhone 6s, I get the following Error Message:
"There are purchased items on the iPhone “XYZ” that have not been transferred to your iTunes library. You should transfer these items to your iTunes library before updating this iPhone. Are you sure you want to continue?"
How do I 1) locate those particular purchased items? and 2) How do I transfer them to my iTunes Library?
iPhone 6s Plus, iOS 9.2.1
