Shared photo albums show no content on MacBooks
I have two MacBooks, both have the absolute latest software installed (Tahoe 26.3), and on both, none (and I mean none) of my shared [photo] albums have any content whatsoever.
Some shared albums, that are shared by other people have content -- but not the MacBooks.
Those same shared albums have content on my iPhone and on my iPad. But they have no content whatsoever on either MacBook.
The rest of the photo albums are on both MacBooks.
What is going on and how do I get the MacBooks sorted out?
