In a workstream it is possible to set multiple languages to make sure messages are in line with the language of the customer for example provided to the workstream by a bot.

This works as expected for quite some features and seems to offer what MS states "a multilingual contact center solution" (https://learn.microsoft.com/en-us/dynamics365/customer-service/administer/voice-channel-multi-language-contact-center).

But apparently the transcripting for voice calls in the workstreams also uses the primary language of the workstream. Meaning that the transcript is worthless if a customer speaks a language not set as priamry but other language in the workstream.

It should be possible that what is currently already language dependent in the workstream, is also in place for the transcription.
