When you purchase a domain on Yola, it can only be published to a site in the account where the domain was purchased (and an account that belongs to the person who owns the domain). If you would like to use the domain on a site in one of your other accounts, we will need to make a change on our side before you can do that.
Please get in touch with Customer Support and send us all the account information and domain name you're wanting to transfer.
Please note that we are unable to assign one of your purchased domains to an account that does not belong to you.
