How do I remove a Domain from a studio?

I have just updated my domain name from the main domain to a subdomain. How do I remove a Domain from a studio?

You can remove domains by clicking the trash icon in the domain dropdown. I have attached a screenshot.

There was a bug earlier this week where users were unable to remove pre-existing custom domains from cloned studios. If you are experiencing this issue, please let me know and I will help you resolve it.

Thanks for your reply.
