Netlify DNS not serving specific records (iCloud mail) - in UI but absent at nameservers

Site: vigilant-heisenberg-ad1832.netlify.app
Domain: alanlong.design — DNS hosted on Netlify (nameservers dns1–4.p09.nsone.net).

Several DNS records show correctly in the Netlify DNS panel but are not being served by your NS1 nameservers. This is not a propagation delay — it has been over 12 hours, and I have already deleted and re-added every record. It matches prior cases where Netlify’s DNS servers were “responding incorrectly directly” and support re-synced the zone.

Resolving fine: the apex A / NETLIFY records and the _dmarc TXT.

NOT resolving (present in the UI, absent at the nameservers):

dig MX/TXT/CNAME @8.8.8.8 returns only the SOA (no answer) for these. Please could you re-sync / fix the zone on the NS1 backend so these records are served?

Thanks,

Alan
