I am buying a license to renew access to Meraki MR18 but have locked myself out of the Meraki portal. I am the only administrator and deleted the yahoo account used to register the device last year and would now like to use my domain email account to manage this device After I buy the new license do I have to re-register with the new domain email account or is there a way to unlock the account without old email address and update the license in the portal.   Thanks ...
