Merge photos from two Apple IDs
I have 2 Apple IDs - one is my regular email address and the other is an iCloud address established years ago. I just got a new phone and have come to understand that of my nearly 6000 photos, all but 200 are on the iCloud address login which I never use. So if I’m logged in with my regular email address, I can only see those 200. I have to log out and log back in with the iCloud address in order to see the full 6000. Is there some way to merge them into the preferred Apple ID?
