The problem I frequently run into on various platforms is shows with some occasional foreign language that is meant to be subtitled. I end up getting either no subtitles (and it takes me a while to realise that I'm meant to understand) or I turn subtitles on and suddenly all the English is subtitled too, which I don't want. I don't get why this is complicated.
