I have transferred several domains from external to Cloud Domains and there seems to be a problem with the contact data verification system. The contact data verification emails (Titled “Google Domains: Confirm Registrant change”) contain a link “Confirm Registrant Change” that goes to “My Domains” in the context of Google Domains, which does not know about the Cloud Domains.
Edit: Even after clicking the links, which open the empty “My Domains” page, the Cloud Domains overview still shows “The registrant email address has not yet been verified” - Any help would be appreciated
