When adding a registering a custom domain I get the error: “A DNS zone for this domain already exists on NS1” error trying to create DNS zone “zecongliang.com”
I contacted NS1 in response and they sent this to me:
"As Netlify uses NS1 as a DNS provider, removing the zone from Netlify also removes the zone from NS1. If you are indeed the owner of this zone, we recommend providing proof of ownership to Netlify’s Support Team and requesting them to remove it if it is indeed within the wrong account.
We cannot make any changes to this zone due to its existence within Netlify’s account."
