We are also changing how remote playback works for streaming personal media (that is, playback when not on the same local network as the server). The reality is that we need more resources to continue putting forth the best personal media experience, and as a result, we will no longer offer remote playback as a free feature. This—alongside the new Plex Pass pricing—will help provide those resources. This change will apply to the future release of our new Plex experience for mobile and other platforms.
I’ve got to admit that I’ve never used Plex (I’m a cantankerous open software fanatic), but how do you get your media on there? You’re hosting your own server so presumably you’re downloading the media somehow. Are you doing it manually? If so, you can do the same with Jellyfin. Is it automated with some tool built into Plex?
