@cgrcavusoglu It’s not an automated process, although I made a feature request for it to be so.
To solve your issue:
- Ensure you really have followed the guide that you’ve linked
- The value should be:
https://answers.netlify.com/t/your-domain-name-is-being-used-by-someone-else-error/123687
- Provide the domain name
Once the team know the domain name, and that you’ve added it, they’ll check, and if it matches they’ll remove the domain from whatever other accounts it may be in.
