Photos won't sync from Mac to iPad via iTunes
I had previously synced my photo albums (thousands of photos) to my iPad. Fine.
When I synced my iPad today, to update some things (including photos), I would that al the previous photos on the iPad were gone.
And when I go into the Photos tab on iTunes, and select toe albums to sync, and "Apply", nothing happens.
On my Mac, photos has maybe a hundred albums and thousands of photos, but when i am in iTunes trying to sync , where you get to select what folder or thing to sync from, when you click "Photos" it shows 0 photos.
What is going on, and how do I get my photos to the iPad??
Thanks
iPad
