I’m did try the new features and it’s working fine but i have one query that i can’t maneually select the subtitils which means “more” options is not showing for me .
Let’s maybe start with pointing out which client you use that doesn’t show the new feature.
Also… which version of the Plex Media Server / the respective clients do you use?
You are running the correct versions of PMS and Web. Just need to wait. Once the feature is available for you, selecting the subtitle section, there will be a “More” option at the bottom of that list.
PMS does not include the newest version of Web. We try to ship stable versions of Web along with PMS since this cannot be updated separately from PMS, so if there are problems with the latest version of Web, they don’t need to wait for an updated PMS. You will need to use the hosted Plex Web for now.
