Suddenly autofill of email address is preferencing one I seldom use
I almost always use the same email for my spouse whom I email multiple times a week. Suddenly, autofill is filling in a seldom yet, active email for him. How can I switch back to the autofilling in of the address I predominantly use (1000s of times/year vs 1-2 times/ year for the other). I have to manually change it each time and sometimes I forget; since he seldom checks that email he doesn't get the required information. I cannot delete the seldom used address because there are rare times we do wish to use it.
