Since the latest update it sort of messed a few things up. Well my wife has the iPhone 6 plus. When she is sending out an email it doesn't show "her" email address in the box. It shows the "to" but not the from. I looked in settings but didn't see anything to fix it. I also googled it and either were older solutions or I didn't understand it. It has to be something simple. thanks for a solution.... By the way nothing to do with this issue but I had to call apple care about another issue with her phone yesterday. Her email icon and the mail settings were completely gone. I couldn't figure out how or why. Well anyway the tech suggested looking in the app sore type search for "mail" and sure enough the mail icon was in the cloud. I just re downloaded it and all was well. I did have to delete her account and re add her email information afterwards though.
