Hello, I open a case ticket number 40350874 since 07/27 and I have not received any updates. The only thing that happened is the reply time changed after a week from 24 hours to as soon as possible. I do own seven Shopify stores and I am trying to change the owner in all of them to have the same email. I get the error that the email is already in use. Does anyone has any idea how to solve this problem? I already created an staff user that works in all seven stores. How come I cannot do the same as the store owner?
