Hi team,
My site: welcome-in-jordan-jo.netlify.app
Team: welcomeinjordan
Domain: welcome-in-jordan.com
Error: welcome-in-jordan.com or one of its subdomains is already managed by Netlify DNS on another team.
I added TXT verification:
Host: verified-for-netlify.welcome-in-jordan.com
Value: https://answers.netlify.com/t/support-guide-verifying-domain-ownership-for-netlify-custom-domain/17864
DNS checker: https://dnschecker.org/#TXT/verified-for-netlify.welcome-in-jordan.com - all green 
Please release it from the other team.
Thanks,
Haitham
