My Favorites Mix suddenly not updating on all devices

I have been enjoying Apple Music for a couple of years now, and I enjoy the weekly automated Mix feature, especially the Favorites Mix. For the last two weeks or so, however, the Mix isn't updating. The problem is the same on all devices, iOS, MacOs, and Windows. I noticed someone posted about this last year, but with no posted workaround, and with comments ranging from "it resolved itself" to "i have the same issue."

I am re-posting the question in the hopes that someone has since figured out how to resolve this issue. Thanks in advance for any assistance or insights.
