Hoping someone can chime in with some help on this one. Hardware involved: MacBook Pro, iPad, iPhone. All running latest software. All using iCloud Photos. Both Photo Stream and photo sharing are disabled. To help illustrate, we'll say album names and counts are: - Album One (1,500 photos) - Album Two (310 photos) - Album Three (29 photos) - Album Four (55 photos) For some reason, intermittently (though several times now), I've noticed that albums duplicate on my iPhone only but are empty. Not my iPad. Not my MacBook Pro. Just the phone. So now it's: - Album One (1,500 photos) - Album Two (310 photos) - Album Two (0 photos) - Album Three (29 photos) - Album Three (0 photos) - Album Four (55 photos) The empty albums are not visible on any other device. If I delete them, it deletes both the "real" and empty album from all devices / iCloud. To attempt to remedy, I've disabled iCloud Photos on the phone, which left some albums left on the phone, inexplicably; deleted everything, restarted, then reenabled iCloud Photos. This deleted most but not all of my albums from the cloud. No idea how to best approach this. Third time now. Appreciate any advice.
