trying to add additional voice enabled units to existing system. I originally created an Amazon account for the purpose but no longer have access to its associated email. When I try and add new units it links automatically to existing old Amazon account and states its sent a verification email to my redundant inaccessible account. I don’t seem able to break this auto completion of existing Alexa account . Tried deleting all existing voice account links and starting from scratch to use new Alexa account but I can’t break out of the precompleted old account details- help please
