Did you set up the redirct in a vercel.json file?

Yes, I did have redirects in my vercel.json file a few weeks ago, but I've since removed them. My current vercel.json only has rewrites configured. However, the redirect is still happening even though I've removed the redirect configuration from the file. Could there be a cached version or deployment that still has the old redirect configuration?

Digging into the data, it looks like schoolofcinematics.io is assigned to a project called schoolofcinematics-redirect. You can remove the domain from that project and add it directly to the project that has the content you want to use.

If you still want to keep it on the redirect project, you should remove any vercel.json redirects included in that project.

I hope that makes sense!
