Hello Netlify Support,
My custom domain kcmaven.com is trapped on an old Netlify account that I previously deleted. I am getting the error that it is already managed by Netlify DNS on another team.
I have moved my nameservers back to Hostinger and successfully added the verified-for-netlify TXT verification record to prove my ownership.
Please manually delete/purge this orphaned DNS zone from your backend system. Thank you!
