Plex server no longer automatically updating libraries since joining beta

I recently started using the beta builds of the server, I’m currently on 1.11.2.4772 on Mac. When I started using the beta builds, Plex stopped automatically updating libraries when content is added or changed. I haven’t made any other changes to my setup, other than installing the beta build.

In the Library settings, “Update my library automatically” is checked, and “Update my library periodically” is unchecked. In the past, this simply worked. But like I said, now that I am on the beta, it is no longer working.

I did a search on the forum and found another thread where it was suggested that “Refresh all metadata” should be tried. I did that, but it didn’t help. Any ideas? What else should I try doing? Or is this simply a bug in the beta builds?
