Memories not working
Just upgraded to MacOS Sierra and the new Photos. Choosing Memories just reveals a message saying 'Memories will appear here when more photos and video are added to the library (I have over 5000). Also when choosing People I am told '0 Photos Scanned' Photos will continue scanning your remaining 5,166 photos when you're not using the app' When I click on 'View People Album' I see all the people previously identified in the old version but as soon as I click on any one of them I am shown the Places that the photos were taken and then the spinning wheel appears as though the scanning process is beginning. So far I have left it overnight but still no change. I have tried rebuilding the library. No effect. Any suggestions?
