It knows what photos are supposed to be there. The thumbnails are grey boxes and when I try to view them I get a blank screen. I followed Apple's instructions for moving it. I designated it as the system library. I have tried rebuilding the library but, it didn't help. If I share something now it generates a thumbnail but does not upload the file.

Do you have iCloud Library enabled and, if so, do you also have "Optimize Mac Storage" enabled?
Also are you running a "managed" or "referenced" library?
Thanks for the quick reply.
That seems to be helping. The thumbnails gradually came back. There is no meta data and when I view the photos or watch the videos I just get a big version of the thumbnail. Videos do not play but, if I mouse over the thumbnail the video plays in thumbnail size. Looking at the Activity Monitor shows little or no network activity.
Hi Tony
I didn't know that about meta data on shared photos - thanks
It IS working!! I have quite few shared photos and videos so, yes, it just took a long time.
I think your tip to switch sharing off and back on was the trigger - thanks
Try turning off shared albums (in photos preferences>icloud) and then turning it on again after a few minutes.
I'm not surprised there is no metadata - as I understand it that is stripped out for shared photos.
How is it looking now. I know Icloud can take a Looooong time to sync lots of photos - sometimes days, and you need to keep photos open while it is doing it.
I do not have iCloud Photos enabled. The size of my library (560GB) and upload speed make it unreasonable.
Here are my preference settings -
after moving my library all of my shared photos are blank
