When you have the captcha qr scanner setup for a qr code at “home”, it will automatically disable when the location of the device moves “x” amount of distance from “home” location where qr code is. (applicable to scenarios when woken earlier than set time and no longer near qr code for alarm dismissal). The only current solution (that I am aware of) is to restart the phone to dismiss the alarm and completely quit the application.
