HelloI am testing out using Sign in with Apple on a web page.I have followed the instructions to add a domain, verify a domain, create a Service ID and link it to an App ID.The domain is verified and everything required in the Developer Portal has green ticks and appears OK.When clicking the sign in button generated on the web page, the sign in modal appears with select email etc, pressing Continue with Touch ID works but then it just says "Sign up not completed".Is there any way to debug this, get a better error message etc?Some notes:1. The registered domain is a top level domain (http://y.com), the page with the button is hosted on a subdomain (http://x.y.com)2. The domain does not have SSL set up on it3. The App ID is for an app that is in development - it is not on the App Store.ThanksRob
