German transcription not working

[dk-demodern]

We've been using dictation for several months now but it seems as if recognition of german language has stopped working.

I'm using the Voice SDK Dictation package for Unity and even if I use the DictationSampleScene and drag the different Wit Configuration assets into the App Dictation Experience component, the english samples understand english but the german samples don't react to anything and just timeout after 15s.
