iCloud Photos Could Not Be Turned On
I am trying to turn on iCloud Photos for my iPad, but get the message in the post title, with "try again later". I have a lot of photos sync'd to the iPad from my iMac, which already has iCloud Photos turned on and the library is fully up loaded from the iMac.
When I toggle iCloud Photos on, on the iPad, it says "Photos Synced from iTunes will be Removed ... 28,209 photos will be removed". So I grit my teeth and select "Remove Photos". And just get the message above. I have seen others raise this issue, but no successful answers.
I recently changed the iTunes sync from USB to sync over wifi. I thought it might be a causing a conflict, so I turned it off, but I still can't turn on iCloud Photos.
Anyone found a solution to this problem?
