I changed my login email address for Cloudflare, so I wanted to update my domain’s registrant info as well. When I created a request to update my email under Registrant Contact info, I received emails on my old and new email addresses. But if I click on the link, I see the message
Change of Registrant Contact Request
There was a problem with your request. Please click the link in your email and try again.
I’ve canceled the request and retried many times but cannot get past this issue.
