I have recently changed my email and have updated it on Stack Overflow under:
Edit Profile & Settings → Email Settings → *Edit Email Settings**
My email shows as having been updated (and yes, I have reverified it); it also states it affects Stack Overflow + 19 other communities.
However I am unsure how to go about updating it elsewhere, such as:
Edit Profile & Settings → Site Settings → My Logins
Under this heading the Stack Exchange option shows my old email, but it doesn't show an option to change it? Other shows my new email.
Additionally, when I went to apply for a job, it still auto fills in my old email - how do I change this there too? Maybe I'm blind, but I couldn't figure out how to edit my email for that anywhere?
