Subdomain not pointing properly

I have set up a subdomain to point to my plasmic app, however, plasmic tells me that the subdomain is being used elsewhere. Any idea on how to resolve this? Here is a screenshot from and plasmic:


Hi @coherent_piranha! The error indicates that the domain is used somewhere else in Vercel. Have you setup some project there (at using that domain before?

No. This is the first time I’ve used this subdomain.

Correction: I see the parent domain in my vercel account, but not the subdomain account. Let me try removing the parent domain to see if that works.
