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 see. So if you read that instruction you’ll see it’s the exact same setup that I outlined. They use a vpn to connect your client to your server and just negotiate the meeting in the middle. It’s the exact same risk scenario as running a reverse proxy on your own vps. Unless I’m missing something else?
