New interface problems! Please fix this!

WHY do you completely revamp the user interface without asking people about it or at least giving them they option to return to what had been working for a decade???

I now have to tap FOUR times to get to any one inbox, instead of simply tapping on the inbox in my account overview. What the hell, people? You’re supposed to make things easier, not cumbersome!

How do I get back to see all my email accounts on the first screen? I do NOT want to have to go into the menu to select one account at a time, that is a complete waste of time. You have no idea how disappointing and infuriating this is !
