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 just reinstalled the latest version of Jellyfin and installed the Media Segments Provider, and tested every client available for it and none of them appear to have a skip intro button implemented.
Most clients have it disables by default and you’ll still have to install the intro skipper plugin.
