Is a bug causing the "Faces" album to not be removed after using iCloud photo?
Before I started using iCloud photo (and thanks for your tips - the air drop thing is magical in a way!) I synched my iPhone with Aperture and there are some photos in the Faces album.
The moment I switched on to iCloud photo, this Faces album should have been removed but it stayed on with no photos in one empty subfolder. I guess Aperture / iTune do not work well to remove this one. Wonder if there is a way to remove this album (not possible on iPhone - it is treated like, err, Video, Burst, Favourites albums).
Could it be a bug? I might have to live with this 'souvenir' forever, unless I remove iCloud photo and redownload everything again..... which I do not want to do.
