Please delete the stale wildcard cert and reissue a standard certificate

Site: financial-snapshot.netlify.app
Custom domain: quidcoach.com (+ www.quidcoach.com), using Netlify DNS.

Error: SniCertificate::CertificateValidationError: Unable to verify challenge for *.quidcoach.com: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.quidcoach.com

The certificate expired on 29 July and the site is now serving the default *.netlify.app cert, so visitors get a full-page NET::ERR_CERT_COMMON_NAME_INVALID warning.

I do not need a wildcard — I use no subdomains other than www. Please delete the stale wildcard certificate, flush the SSL provisioning state, and issue a standard Let’s Encrypt certificate for quidcoach.com and www.quidcoach.com only.
