iPhone not uploading photos to iCloud Photo Library. Why?
I have 2 iPhones 6Plus's both fully updated. I have enabled them both to use iCloud Photo Library. One has synced up nicely, the other has not pulled any photos down from the cloud and says that it has 2,373 items to upload. Any ideas what could be preventing it? I have tried toggling iCloud Photo Library off and on with no success. Any thoughts would be appreciated. Thanks.
iPhone 6 Plus, iOS 8.3, iCloud Photo Library
