So I do have a large Photo library in excess of 120 GB and over 35,000 photos. I am also on the public beta. When I first transitioned to the Beta most of the faces transitioned but then it got stuck and never finished. It was in the 28,000 range. I ended up having issues with my account because of the forced move back to a local password so I created a new account for myself and started fresh. On the new account I did not move or transition anything over from the original one. I let the photo database rebuild from iCloud and once it was done, it started to scan for faces again. It stopped scanning yesterday morning around 9am "Finding People 4995 of 35730 items processed" I have tried restarting photos and restarting the computer but it does not want to kick in and continue. Has anyone else experienced this yet?
