Can't switch from Calendar month view to day From the calendar month view, I can't select a date, and jump to the day view.

Running iOS 9.0.2 on iPhone 6
It depends on whether you have the 'overview' icon at the top of the screen on or off.

If it's On, your day view is underneath the Month...  





If it's Off, then tapping a day will take you to the Day View  





unless the same icon is also On in Day View, in which case it will go to Event List view
