Deleted project causing a "Another project is already using this domain error" error

Hello,

I’m trying to map theappengineers-www.netlify.app to www.theappengineers.com but getting a Another project is already using this domain error.

It was mapped to youthful-ritchie-3555bd.netlify.app which was owned by my account but automatically deleted.

Please can you free up the domain mapping so I can map my domain?

Many thanks, Tom

Bumping this as it doesn’t look like anyone has seen it, is this the right place to get support (feels odd providing account details on open forums)?

Coming up to a month on this one, please can someone respond?
