Google's help section regarding "Find faces" says:
- Go to photos.google.com/search.
- Under the People section, click a person's face to see photos that include similar faces. (If you don't see the person you're looking for, click MORE.)
When I go to the search section, I see "Places" and "Things" - no faces! And I'm sure I have faces, I used Google+ until now with plenty of face-tagging.
Which also brings up an interesting point - how do you face-tag in this new interface?
