iCloud Photos not downloading
Randomly when I try to attach A pic or video to an email or text I get the error "photo can't be downloaded from iCloud, please try again later." I have it set to store origionals on iPhone. I have an iPhone 6+. I understand it's a sync service, what I don't understand if there is a copy on my iPhone why/how would I get this error. It shouldn't have to download anything. And this will go on for days at a time.
Any ideas?
iPhone 6 Plus, iOS 8.2
