My Apple ID old Email still appears even after updating it in the Apple ID account
This is my very first post and I am somewhat of a rookie. I am using an iPhone 15 and needed to change my Apple ID e-mail address. I searched for help and the web said to go to settings, my name, sign in and security and edit the e-mail which I did. However the old e-mail still appears. I tried a restart of my phone. Find My phone got turned off (I have since turned it back on). E-mail below is no longer in service. How do I change this? Please help the rookie. Thanks in advance!
