I have localizations for "en" and "ru" languages, and if user select any other language (fr,de...) I need to display Russian localization variant. I tried changing "Localization native development region" in info.plist to "ru" / "Russian", but it always displays English, when using unsupported language. There is related question from which I'm assuming this task is impossible.
I would be grateful for any advice and insights on these issues.
