New Email/Old Apple Id
I have a new email address. The prior email no longer exists. I followed the instructions on the Apple site, for changing my apple id from old email to the new email address on my Iphone 10.
When I go to settings on the Iphone, it still shows my apple id as my old email address. I rebooted my iphone, but that didn't help.
I read somewhere that I needed to turn off "Find My". When I try to do that, it displays the prior Apple Id. I enter the password for the prior id, and I get a Verification Failed message stating that my Apple Id or Password is incorrect.
How can I get my Iphone to use my new Apple Id (new email)?
Thank you.
