Hey,
No, it’s all Plex apps. Tried it on plex web app, two different android TVs, an iPhone and an iPad. All show the same thing and yes, if I play it it really does play the English track, or has English subtitles on if no English track exists.
All have the first track (the original language) correctly tagged as default and all language tags are correctly set as well. So far, on that user, no audio or subtitles were ever manually changed.
Here is part of the XML for just one example. In this case, it’s a French movie and the user’s account skips over the French audio track to select the English audio track.

If the user is on an English speaking movie, of course, the behavior appears fine, as it selects the English track. But if the user changes the audio track to another language, it auto-selects the English subtitles. This behavior would be expected if we had set English language preferences in the account settings, but yeah, we never did. I just don’t know what I need to do to stop this, and make it behave like my own account!
Thank you!
