cc @bbondy this appears to be a problem on linux as well. Will brave/brave-core#604 fix it for linux as well?

System Language is English and Brave Language is also English

Changing the Brave Language to German does not change the Language at all 🤔
(I just tested this in Chromium 69 and changing the language does not work too, so it looks like a chromium issue)

[bbondy]

The last fix was definitely only for Wibdows, I'll check it out. Note some more work needs to be done to actually add the diff languages, but I'll do just the i18n label fix here.

Changing the Brave Language to German does not change the Language at all

You need to do the following for browser language to change on Linux

• Add language packs from system settings
• Change Language from settings and restart
• Add preferred language in Browser and relaunch (Available languages might not be completely translated)

Please open a new issue if that doesn't work. Better to track one item per issue rather than combining multiple
