I'm trying to change the email address of my Apple Store AppleID. I can add a new email address, but can switch the addresses. It keeps showing the message below, but no instructions how to do it on my devices.
iPhone 15 Pro Max
Refer to the support article Change your Apple ID - Apple Support
I have never seen that message you show but to me it is saying you are trying to do this using a web interface. Try doing it using the method in the link above directly on a trusted device.
Unfortunately, that isn't going to work. I have 2 Apple IDs - One for iCloud and another for purchases. I'm trying to change the latter. It doesn't show up in that section. I'll try contacting Apple support. Thanks for the help!
