I am learning Hebrew but I find that many Hebrew Netflix shows do not offer English subtitles. It's really frustrating.
Also, I happily watch dubbings. Dubbings are easier to understand then original shows. Imo, it is fully ok to watch Nordic show in Spanish. Or an American show I have already seen, but this time in Spanish.
After about 6 months I became proficient enough to drop the extension and just watch now in plain spanish audio and - depending on the content - spanish subtitles.
Hebrew is a very niche language, so it won't fix the core problem that there is no hebrew-native content.
I ask because I went down this path a little to help my German learning, but struggled to find the right combination of videos at the right level with the right subtitles available. (I was trying to use free apps/services though).
Having 2 subtitles is only helpful in the beginning, where you do not understand entire sentences or sentence constructs sometimes, but you want to understand that entire sentence to continue to follow the storyline (and continue to be engaged). Very quickly I switched to having only the spanish subtitle and lookup individual words.
IIRC, Languagereactor also enables all the subtitles (netflix somehow filters the list of available subtitles based on the country you are in). But I should add that I am actually living in spain, so all the content has spanish subtitles available (and english, which I used as a reference instead of german).
