Same for Belgium, Google/Apple translate has never been able to correctly translate French and Dutch for us while our vocabulary choices are drastically different from neighbouring France and Netherlands.
For people with their iDevice set to the Swiss/Austrian German or Belgian Dutch locales, Apple Translate initially didn't even offer their languages in Apple Translate (i.e. not even German or Dutch). Only after internal complaining did they allow Swiss/Austrian German users to use German in Apple Translate.
