Actually I'm using English locale but when I test the app in Russian locale which does not have translations yet - everything works correctly in English locale as fallback locale. However relative dates in timelines ("written XX minutes ago") wrongly falling back to Belarus(!) language. After digging the code I see Belarus locale-data is imported first and I think it will be picked up for all languages which does not have translations while it should fallback to English.
