Unless I’m missing something, I can’t see how to get my target language (Thai) to show up in the Subtitle panel when watching an English language movie. I want to be able to watch English movies but see the target language subtitles in the subtitles panel. That way I can learn my target language while also watching English movies and series I want to see anyway. Is there a way to do this? If not, please add it! 
Hello, if Netflix or Youtube dispose of the Thai subtitle, you should be able to switch in on in the language reactor setting : “Netflix Subtitle Language”.
Can you send us a link of the video you would like to have the thai subtitle, as well as telling us from which country you are watching it ? (netflix has different subtitles for a same movie/show depending on the region you are).
Thank you !
