I've been trying to update the email address on my account for transaction notifications (via Preferences). It is an old email address and not the one that I login with. I've tried from my iPhone and Mac, but even though I get a message that says it has been updated, it does not stick. I've chatted and talked to several representatives with no resolution and am now just getting a daily email with my case number when I ask for a response. Has anyone else had this happen?
