Sometimes it just takes a little while for domain updates to propagate. It looks like the nameservers are correct now. Are you still having trouble with it?

yes. id did this over a week ago. i also have this domain in firebase for email authicaution and have added the proper records in vercel. ( I think) LOL. Yor can enter my account if you need to you have my full premission. If you need anything else please let me know. I really appreciate your help!

I see what's happening now. The nameservers are correct for use with Vercel. But the added A record points the root domain away from your Vercel deployment to Firebase instead. You'll need to change that configuration, or use a subdomain or a different custom domain for one of the projects

Please let me know if you need more info or have any other questions!

Hey, if you remove the A record that is set to > 199.36.158.100 it should work

Looks like that is conflicting at the moment, I see the nameservers propagated correctly but they have that set as a record
