Photos identifying, but not naming faces
Photos will not recognize faces in my photos that are very recognizable. It identifies the faces, but there's just a circle around the face labeled "unnamed."
For example, I have hundreds of very clear, close-up photos of my grandson where I've added his name to the "unnamed" circle. But it still doesn't identify him in new photos I take.
It's not only happening with him, but many family members in very clear photos.
How can I force it to recognize these people? (I'm using a MacBook M1 pro, Monterey OS).
