Thanks!
About the settings… the translations available depend on the movie you are watching, if Netflix has subtitles available for that langauge. But I would be suprised if what you are watching doesn’t have English subtitles…
Actually I took the movieId from your screenshot (80094357) and tried it here. Yes, there should be English subtitles.
From your first screenshot, I think I know what the issue is. Shouldn’t be too hard to fix.
