Ok thanks
My other question is i have plex pass and i see on the forum people are using the enhanced plex app on apple tv, in the plex settings i dont see any option to use the enhanced player. I have it turned on on my iphone and ipad.
I think that was a thing when the enhanced player has been newly introduced. Currently it’s enabled by default but you can still disable it (there’s very few use cases for which users still do that). From what I understand this feature will be removed at some point.
Open the settings in Plex for tvOS
Scroll to Advanced > Disable Enhanced Video Player
You only get that when playing a movie with an external SRT subtitle.
If you’re using some embedded subtitles, you should manage the offset using the stream’s meta/header data. https://support.plex.tv/articles/subtitle-offsets/
