Sometimes when an app is upgraded through the Play Store, the icon for it in the launcher no longer points to the app. Other times, it works fine. What's up with that? Seems totally random for which apps it happens with and when. Why does it happen?
Update: Andrew asked what happens if it doesn't point to the app. Great question. The launcher presents a dialog box that states: "Item is not installed. Search Google Play, or pick another app?" It has three buttons, which are: Cancel, Select app, Play Store. I also should mention this happens on multiple devices running KitKat.
