For anyone interested, Jellyfin (which you can easily install next to, or in place of, Plex) seems to have a similar Watch Together feature. I haven’t tried it out, but it might restore this functionality to some degree.
This is a theme in App Store reviews. Here’s a thread with a (small) sampling of recent reviews showing how much we hate Plex’s recent decisions. This will absolutely continue to tank Plex and fuel Jellyfin to grow and eventually replace it:

Super sad for those who believed in and supported Plex.
