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.
It has to do with the app used. I think it will work with web player and maybe the windows app, but it won’t work on Android/iOS.
oh okay, interesting. well, you could always use the web browser on your phone/ipad i guess. not a great experience but i know for a fact that plex works on ios in chrome at the very least.
