Title: Certificate provisioning is blocking a primary domain change

My Netlify site is:

rustic-innovations.netlify.app

The incorrect primary domain is:

enroottourslux.com

The correct primary domain should be:

rusticinnovations.co.za

Netlify has been provisioning a certificate for the incorrect domain and now displays:

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

This has remained stuck and prevents me from changing or removing the incorrect primary domain. The correct domain is using the Netlify nameservers:

dns1.p05.nsone.net
dns2.p05.nsone.net
dns3.p05.nsone.net
dns4.p05.nsone.net

Please clear the stalled certificate-provisioning process and allow me to change the primary domain to rusticinnovations.co.za.
