MailChimp asked to authenticate our domain by adding CNAME records. So far, Mailchimp seems to have authenticated the records, but when I do a NS query on the many NS checkers online, none of them could read my CNAME records (they could read my TXT records). How come? It's been 24 hours. I'm using CloudFlare, and I've already added the same CNAME records there.
