Add sub domain problem

Hello, I’m using Netlify to host my website, and I received a messa ge from IEEE regarding the sub domain we requested. However, when I try to add my sub domain “” to the domain management, I encounter this message: “ or one of its subdomains is already managed by Netlify DNS on another team.” What should I do?

The thing you must not do is open multiple topics for the same issue. You’ve duplicated your previous post to which you received a response with information relevant to overcoming it.
