We have a unit that was claimed to be sending false notifications..... No one pushed the button, yada yada yada. Crazy client so who knows. DB sent a replacement button. We have not heard from her since.... But we also had her uninstall and reinstall the app at the same time. Not sure what the problem was really but DB thought maybe the button was flaky.
Easy to pull it out and test continuity.
