I am using a custom domain to access the app for example: example123.com. The custom domain is applied using CNAME DNS records.
Some of the users are hanging on login, and when I check the logs I can see that there is an callback URL mismatch error.
In the auth0 application I have allowed callbacks to example123.com, but some users are being redirected to master.123456.amplifyapp.com (the non custom domain version) which I dont know why?
What is the reason a user would be redirected to the original URL and not the custom domain URL? It only seems to happen with some users.
Thank you for posting your question on Auth0 Community! Usually, after successful authentication, users are redirected back to the callback_url sent in the initial Authorization request. Those who get redirected back to the master.123456.amplifyapp.com URL, are they using a bookmarked authorize URL?
