I am using the default back button for UINavigationController (not setting any hardcoded text anywhere). My app is available in multiple languages. I noticed that the Back button gets translated in certain languages and not others.
For example, if I switch to French then I see "Retour" which is the correct translation for back. But if I switch to Bulgarian, then the button says "Back". Does Apple only provide OOTB support for certain languages and not others? Where can I find this list, if it actually exists?
