Photos in Album and Recently Saved but not in Library
I moved about 200 pictures from a shared google drive into an album in my Photos app, on my Mac (Sequoia 15.6.1) . The reason that I copied them straight into an Album is that they are all of a single event and I wanted to see them as a slide show. I see the same pictures in the Recently Saved, but I was surprised when I noticed that the same pictures are not showing in my Library. I have tried some of the suggestions that I've seen on other threads. I made sure that the library is set to show "All items", I right clicked on one of the pics in the Recently Salved and "Show in All Photos" is greyed out.
When I try to sync my Lybrary, it shows that there are 204 pictures to be synced, but it has been stuck on sync for hours and with no progress.
