I don't know if a netflix engineer reads this:

I still have an issue that I can only watch some series/movies (e.g. sherlock holmes series) only in french + english, while my friends can watch them in english + german. All in same country (Luxembourg).

Changing the language on the tv and resetting netflix (konami code) changed to the "german" version. But now it's back to english + french.

Best thing would be to have access to all 3 languages here and not make any choice/guess based on tv language or browser environment
