Unable to reclaim vercel.app subdomain after deleting original project

Hi
I’m having an issue reclaiming a vercel.app subdomain that I originally registered.
Here’s what happened:
I created a project with the subdomain lifetracker.vercel.app
I later created a new project and encountered a naming conflict
I deleted the original project, expecting to be able to assign lifetracker.vercel.app to my new project
When I try to rename my current project to use lifetracker.vercel.app, I get an error saying the subdomain is already taken
My current project is named lifetracker and is using the alias lifetracker-sand.vercel.app, but I’d like to switch it back to lifetracker.vercel.app since I was the original owner of that subdomain.
It seems like the alias wasn’t properly released when I deleted the original project. Is there any way to have this subdomain released back to my account?
Thanks for any help!
