DomainTransfer Issue

I’m helping a client who has purchased a business, domain and associated website. We’ve redeployed the site on Netlify in our own account and transferred the domain to our own registrar (less than 24 hours ago). Understandably DNS propagation will take some time to fully complete.

At this stage when I try to add the custom domain to the site on Netlify I am getting the error “xxx or one of its subdomains is already managed by Netlify DNS on another team.”. How long will Netlify take to purge their internal systems of the old domain records or is there something manual I need to do.

We’ve asked the seller to the delete the site from their Netlify and remove the domain and they said they have already.

Update 1) Update as per related articles I’ve added the verified-for-netlify txt record with the value of this post ID. The domain in question is deepshiatsu.com. Could someone in Netlify support please assist. Thanks

Resolved as per the helpdesk ticket.
