Purchases on iPhone not in iTunes library
While backing up my iPhone using iTunes (and I'm using my MacBook Pro) I got the following message:
There are purchases on "David's Awesome iPhone!" which are not in your iTunes library ...
I've attached a screen capture.
Should I take the blue pill or the red pill?
(i.e. Which button do I press?)
Also, I have no recollection of purchasing something through the phone (music, movies and such).
MacBook Pro (Retina, 15-inch, Mid 2015), OS X El Capitan (10.11.1)
