why can't iTunes sync my iPhone or iPad photos
Using iOS 9.0.2 and iTunes 12.3.0.44 and OS 10.11.
I now get an error message when trying to sync both my iPhone and iPad... that "iTunes cannot sync photos to the iPhone “name of my device’s iPhone” because your Photos Library is not yet available. Please try again later."
This has only started after OS and iOS updates to the latest systems.
Why and how can I get my Photos to sync again?
MacBook Pro (15-inch Late 2011), OS X El Capitan (10.11), 8Gb RAM.
