The Google Photos Creations used to be grouped under Auto Awesome. Since the re-branding, Auto Awesome doesn't exist anymore. Is there way to see these things without manually going through all of the photos or albums?
To see the Creations you've saved...
To see the Creations the Assistant has suggested, but which you didn't save...
- Go to the "Assistant" page
- Scroll to the bottom and click "VIEW UNSAVED CREATIONS"
(I don't know if this latter holds on to Creations that you've explicitly dismissed/deleted.)
