OH GOD, people are still complaining about the last time (last year?) you made changes and now you've done it again! The main color is yellow? Then on my phone, at the bottom, there was a 'settings' icon that I could tap and be able to switch between e-mail addresses. Now it's gone, but fortunately, I discovered if I tap on my initial at the top of the e-mail page, the settings icon appears, and I can switch my addresses from there.

QUIT THE CHANGES! It's bad enough that you don't announce changes. Just go back to the original e-mail, before the last change. People were saying that with the last change and that request is still showing as a high priority. So obviously you're ignoring the people and still making changes that people hate!
