How does the App Store handle localized content fallbacks in the store listing, in app products, and game center content?
For example, if a user's language is set to Portuguese (Portugal) pt-PT, and I don't supply a translation for pt-PT but I do for pt-BR (Brazil), will it show the user the pt-BR translation or as a developer, do I need to provide both translations (i.e. all language variations/regions)?
Another example, if I provide translations for en-US and en-GB and the user's language is Australian English (en-AU), will it show en-US or en-GB on the store or in Game Center? I would expect it to use en-GB.
