Firebase -> Netlify: "DNS Zone exists under different account" / "a site is already using this domain"

Trying to move from a Firebase site to Netlify. Deleted the domain records and project in Firebase. Still getting:
“DNS Zone exists under different account” error trying to set custom domain.

Now its saying “a site is already using this domain”. I tried to fix this in my DNS settings by setting a URL redirect to my netlify URL, I hope that wouldn’t create this issue. That redirect doesn’t work so my site ( is hanging.

Hi @lsalvatore!

I think we got this fixed up via email, but let us know if things still aren’t working as expected on your end.
