a few days ago i noticed my plex was using pluto tv as 1 of 2 guide sources. i dont know how i did it but there it was. at the time i never really paid it any notice.
since then ive re-installed plex but for the life of me i cant work out how to get plex to start using pluto tv as i guide source again.
As far as anything publicly known, no, Pluto TV itself has not been added as a separate service within the Plex Live TV guide.
Paramount, PlutoTV’s parent company is a media partner and does have some channels already available under the Plex Live TV guide lineup but nothing has been provided officially, indicating that PlutoTV itself will be incorporated into the guide as a separate service.
Plex has been known to “make mistakes” and accidentally flip switches without notice so bare in mind it most certainly was not on purpose or was intended to stay for long.
Plex will also not verify any of these actions or mishaps until they are fully ready to.
It’s always a good idea to snap a screenshot for future cases.
