I have only one Apple device and nothing else. I wanted to update the notifications email for my Apple account.

I open my AppleID in a web page of Safari on my iPhone.

I follow these steps :

        1	Log in to appleid.

    2	Select "Sign-in and Security"

    3	Select"Notification Email" (the defunct email is displayed)

    4	Select "Change Email"

    5	Enter a new valid email address in the modal popup.

    6	Click continue.  The following message is displayed:


  

"Continue on one of your devices On an iPhone, iPad or iPod touch go to Settings > Apple ID. On a Mac go to System Preferences or System Settings > Apple ID."

When I look in Settings > AppleID ON THE DEVICE there is no option anywhere to change notification email … 🤷🏻‍♂️

People have been posting about this on the official Apple support forum for years with no solution mentioned.
