Sadly depending on which country you're in, some shows on Netflix won't have all the audio/subtitles available. No idea if this is Netflix's fault or yet another unfortunate result of copyright hell.
This happens fairly often on German Netflix. When the program's language is neither German nor English, often there are no English subtitles available.
International licensing is obviously complicated, so it's hard to say whose "fault" it is, but my suspicion is that some rights owners will only license the service to use the local language to prevent end users doing digital geo-arbitrage.
For example, the Swedish series "The Bridge" is available on German Netflix, and the trailer has English subtitles, but the actual episodes only offer German subs. AFAICT in the US market this show is only available for streaming as a purchase from Amazon.
I’ve found that with the plugin https://languagelearningwithnetflix.com/ I tend to get a longer list of options both for audio and subtitles. It also let’s you do fun stuff like displaying two sets of subtitles simultaneously—although that didn’t really work for my brain.
+1 for LLWN! Fantastic Chrome extension, especially for language learning. They also have one for YouTube.
However, the language options offered beyond those already provided by Netflix are machine translated. This is good enough to follow along or fill in gaps in your knowledge of the officially subtitled language, but is a subpar representation of the program.
