When I click on the Android notification generated from the Stack Exchange app, it always brings up the Stack Exchange app, pulls a shade into view from the right side of the screen and displays nothing on it.
If I close the shade and open it again by clicking on the notifications button in the app, it opens up the shade and displays the notifications.
Usually I see the notification that was in the Android's notification shade, but not always.
I'm using Galaxy S4 with OS 4.3.
