iOS Update Apple ID Settings Wrong Email
I changed the email I use for my Apple ID about a month ago. Everything was good until yesterday when I went to change my Apple ID password on my Mac. I changed the password, and then my devices said to update Apple ID settings as usual. On both my Macs this worked fine, but on my iPhone X, it shows my old email. So when I attempt to plug my current password in, it says this Apple ID doesn't exist for that email. I have no way of changing the email that pops up when I click on update Apple ID settings.
I have already signed out of my iCloud and back in, and that didn't fix anything.
Any thoughts?
iPhone X, iOS 12
