Hi @kallurict,
Welcome to the Auth0 Community!
I understand that you are seeing a CORS error after a redirect - I believe you may be running into one of the issues mentioned in this Community Article: CORS error when initiating silent auth requests
Could you please review that article, and check how the redirection is being made by your application? The user’s browser should be navigating to the /authorize URL and not a Javacscript fetch/request.
If you are still having issues, some code snippets of how your application is triggering the redirect would be helpful for further troubleshooting.
Best,
Mary Beth
