I have an alarm set to be dismissed by scanning a tag in my home. I have "only at home" turned on for this alarm. I left for work (a 5-10 min walk away) this morning before the alarm went off. Even though I have "only at home" turned on, the alarm still went off, and I have no way to dismiss it. I've restarted the phone several times, and turned off the alarm manually, but it still goes off a few minutes after restarting, every time I restart the phone.
How can I dismiss this alarm without going home? Why did it go off in the first place?
