Gizmo Watch is calling former contact

[JenkintownDesigner]

I edited the phone number of a contact (I had entered it incorrectly previously) in my son's Gizmo. However, when my son tries to call the contact, it still dials the old number that I had deleted. How do I clear the cache or otherwise delete this old number from the device, when I can't actually do the editing on the device?

Oh wow. You need to reset the Gizmo Watch. It will not reset the settings you have on the Gizmo Hub. You then can click the contacts you have updated on the Hub and assign them to the watch. It was easy. Hope this helps!:
