So this was a frequent issue with my old IPad (Generation 3 I believe). Either the photos wouldn't sync at all, sone of them would/wouldn't or sometimes just a long delay. I got my new IPad Air2 in October and it was greatly improved until last week when we were at Disneyland with my Son & family. Now they aren't syncing at all, not one single photo in the last two weeks, and I have taken a lot!! So very frustrating!! Any ideas before I have to try and call the Genius desk? Anyone else having this issue? Thanks in advance for any suggestions.
