Can't "Select a shared audience" people core services
Hey guys,
When I tried to test the people core service functionality on my campaign instances post confirmation from adobe client care that they have setup the audience sharing from their end I get this error when I'm trying to create shared audience in a list.

Hope that anyone can help me, I tried to look at the adobe marketing cloud external account and can't really find any obvious issue from my end.
Regards,
Felix
