Ipad 9.2.1 not syncing pdf or epub
I just updated to the iOS 9.2.1 in my iPad 2 and now my selected books are not syncing properly. I have reset my ipad to factory and started again and nothing. When I select the books to be added to my ipad it start to sync but the books get deleted from my ipad and dissapear. When I look at the iTunes windows the check box is empty again. I tried many times with pdf and epubs and still doing the same thing. It is an issue with 9.2.1??? Thanks.
iPad 2, iOS 9.2.1
