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’m in the exact same boat. I have a Jellyfin server configured and ready to go whenever something happens to really piss me off. This nearly was it until I saw that my lifetime Plex pass I bought 10 years ago will make it still be free for my family.
