Plex is a popular streaming service that allows you to roll your own server, and it has been beta-testing its new Plex experience (basically, an overhaul of the service, including its UI) for a while now; so far, the feedback has been positive. In other words, we've known a revamped Plex should be landing soon. But with big changes, sometimes older features don't make the cut. Plex recently announced on its forum that its COVID-era Watch Together feature won't be available when the new Plex experience drops.
