Subtitles on the xbox client

[TheDreadPirate]

The only workaround I know of is to burn in all subtitles when watching on the Xbox. If a client tells Jellyfin it is able to directly play subtitles, Jellyfin will simply send it the subtitle track and we rely on the device's subtitle renderer. If their renderer is bugged/sucks, there isn't much we can do except burn in subs.
