When you get a message, it used to show it right on the screen, you don't have to launch the app (like text message). Now they just show the notification. I am not sure if there is a way to get the old style back, I am too lazy to experiment.

This is similar to those stupid emails which would force users to click through, login and then read the message instead of just including the message itself in the email. Which to me is insane.
