Why can't you sort My Albums in Photos. I have so many albums, and I would like them sorted alphabetically or by date, depending on what I am searching for.

Have you tried opening the Photos app, click "My Albums" in the sidebar, click the View menu, click Sort - By Name; By Oldest First, or By Newest First?

I value that +1 Old Toad. I'm usually hesitant to deal with Photos questions knowing that both you and Léonie are in the wings.

You're welcome. I've fallen behind léonie in the Photos area as I don't use iCloud Photos and so many of the questions is about that feature. So I rely on léonie also.
