Where do I turn off subtitles completely/permanently?

Been using the Plex for Xbox One app for a while, and I’m very happy as a lifetime plex pass subscriber!

One nigling frustration is that every time I turn off subtitles, it’s right back for the next episode. I’ve turned off subtitles on the server side (set to none), and set subtitles to automatic on the client side. All languages on client and on my xbox itself is set to English.

I’ve tried so many variations, but the problem persists: The subtitles (when available externally of course) just keeps coming back every time I start a new episode! I’m hoping I’m making a doofus mistake and it will be a quick fix.

The app in fact now ignores all my subtitle settings. When I set it to tiny in preferences, it still shows up as HUGE.

Well if you are making doofus mistake then I am in the same doofus boat!
I have local users and they seem to have this subtitle problem as well as remote users.
When I log on myself locally, … as the admin user I guess … the subtitles are never an issue and subtitles are always off.

Ah, the doofus plot thickens. We also watch everything on a secondary Plex home user account, which is where the subtitle issue is. No luck yet though.
