Re: What about multiple languages?
I note the clutching of pearls generally.
My first thought when I read about this was "If you have a problem matching a supported language then fall back to English as a sensible default.
It is, after all, one of the major global business languages and there is a good chance that anyone using the App would understand it.
Or have a contact who could."
Major software blunder to output nothing.
It also highlights the lack of thoughtful testing.
Or the unwillingness to accept testing results.
