So when I try to change my primary email from icloud.com to gmail, I won't receive a verification request. And it would display after the page reloading as if it is still being edited, still showing the gmail email. I tried changing it in setttings>iTunes and App Stores and from the app store, but it is greyed out and I cannot change it. I am not trying to change the actual apple id, just the primary email. Can I change it?
