If you try to remove a device from your account and it fails to do so:
- Make sure the device is turned on and within range. You may want to turn it off and back one to confirm before you try again to remove it.
- Try several times.
- If neither of the above recommendations work you may need to perform a "Hard Reset" on the device: First, Tap "my device is broken" after it fails to unclaim from the app. Then remove the device from the account by completing a "hard reset" by holding the button on the device for 16 seconds.
