Hi team,
We are using SSO for our applications. Added a custom application to OKTA and also added its URL as a trusted origin. This works fine when registering a user into OKTA from that application (using okta API's). But when I try to assign that user to an Application with another following API call, CORS problem occurs. I am unable to diagnose the issue. Since user registration goes through but user assignment to application blocks.

Hi Alex!
Which is the exact API call used to assign user to an application? If you open the developer console, can you please check what error is shown? I will follow up again on the case we currently have open.
