Update deleted back button

This app was once my favorite news feed app. However, an update for the iPad app causes he navigation button on the top left corner to disappear after you open a few news stories in a particular feed. Thus to continue reading any other content you must completely exit out of the app for the back button to reappear. Digg I rate 5, diggs apps not so much lately.
