Stuck certificate provisioning blocks changing primary domain

Site: iridescent-pasca-ebf618.netlify.app

The wrong domain seasthedaycruise.com was accidentally set as the primary domain.
The correct registered domain is seasthedayscruise.com, and it is already added to the Netlify project as a domain alias.

Netlify is now blocking all custom-domain changes with the message:

“We’re provisioning a certificate for your site, you cannot change custom domains until that process completes.”

Please clear/reset the stuck certificate provisioning so I can make seasthedayscruise.com the primary domain and remove the incorrect seasthedaycruise.com and www.seasthedaycruise.com entries.
