Find the information on how to grant access to domains@ipstudio.co for your domain name.
Sometimes your domain’s DNS might have been setup to some other 3rd party service, in which case you have to invite domains@ipstudio.co to the service where DNS is managed and not on the domain name registrar itself.
If your domain is hosted somewhere other than on the providers list above you can look through your domain name provider’s support articles to find how to invite a new user to manage your domain.
If you are still not sure feel free to reach out to support@ipstudio.co
