*blogofthe.day* or one of its subdomains is already managed by Netlify DNS on another team

I recently took a project over from another person, in GitHub and in Netlify.

The domain: blogofthe.day

Builds are working great. And for a while deploys and the DNS worked. I now get an error, though builds still seem okay.

When adding DNS, I get:
blogofthe.day or one of its subdomains is already managed by Netlify DNS on another team.

Site: https://blogoftheday.netlify.app

The nameserver information transferred over as 4 name servers:

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

I was looking at doing the TXT record for verified-for-netlify but am not sure that applies to my case.

Hi, yes, you will need to set a TXT record. You can do so using the instructions here.
