We are using APIs for creating and updating users in Okta and Cornerstone. If we update the Okta User Name, the profile updates correctly in both Okta and Cornerstone. We create a session from another application via the Authentication API. When we go to cornerstone, it is still trying to use the previous Okta User Name. If I run an application usage report, I see that the Application User Name is still the previous value. How do I update the Application User Name via API?
