From Android user feedback:
I just installed the Wikipedia app and noticed a huge error in the languages list. The language with language code NB is listed as "Norsk", not "Norsk bokmål" as it should. We have two written languages in Norway: norsk nynorsk (NN) and norsk bokmål (NB), so listing one of those as just "norsk" is inaccurate (and is also considered to be very rude). The website version of Wikipedia has correctly listed the language as "norsk bokmål", not only "norsk". Hope you can fix this soon! Languages are important to people.
