I can't create new iCloud acct bcs my email is attached to wife's acct
This Apple Id is my wife's. I want to create a new Apple Id with its own iCloud account, but when I try to it fails because my email account is already in use as her rescue email address. How can I create a new Apple Id and iCloud account using my email address? Do I need to have her change her rescue email address? We have tried to do that but don't know how to edit the account information.
