Hey @kkrp1 , thanks for posting.
If I’m not mistaken, under the Allowed Calback URLs in your Auth0 tenant, you can add wildcard for the subdomain, like https://*.example.com, but not this way https://example.com/*
This docs can be also useful to review - How do I set up a dynamic Allowed Callback URL?
Please let me know if you have any follow up questions!
