I have an API Management instance running where users can login using only Azure AD. There is a single Administrators account, but it is using the legacy User/Password Identity. I cannot remove the user. I want to assign a user from the Azure AD to the Administrators group, but I can not figure out how.
I have followed these steps by Microsoft but they just seem to redirect me to the legacy portal (or the new Developer portal if I change the URL normally) with my default Administrators account logged in.
