Has anyone else noticed this alarm bug on the notification screen? It literally an infinite scroll of duplicate alarms. It appears if I toggle an alarm off/on, and goes away only with a soft reset.
To the OP: I'd go with what others are saying- press and hold the home and power buttons together until the screen darkens and the white apple logo appears. And hopefully that should resolve the issue for you. If it doesn't, then I would suggest a Genius appointment at your local Apple store.
I've done that several times, and it works. The problem comes back if I have to disable an alarm during the week. When I turn it back on, the bug comes back.
