This bug is happening when my 6s upgraded to iOS 10, and also my 7 Plus now. The fact is when there are notifications, I pull down the notification bar and try to click on it, it cannot open corresponding app sometimes but not all the time. All I need to do is clicking on to it using 3D Touch and there will have a pop-up window, and tap that window. Have anyone also facing the same issue or just me? As I haven't find it in the bug and changes thread, thanks!
