How do I return a person to the People Album?
One person's Profile in the People Album had become hopelessly confused with another person. After having corrected many photos, I decided it would be best just to delete the Profile and start again. So, I removed the Profile from Photos.
However... I am unable to find a way to create the Profile again. The person is still identified in photos, however I am unable to add a Profile for them in the People Album.
I tried re-identifying some of the photos with a new name. A new Profile with the new name does appear but all the other previously identified photos retain the old name for which there is no longer a Profile.
