My daughter's GizmoWatch will not allow her to text me. I am assigned as guardian 1 and it shows texting as an option, however when we select the text icon the screen blacks out for a moment then returns to the home screen. My daughter is able to text my wife (guardian 2) without issue. She is also able to call and recieve texts from me. When we attempted to reply to a text I sent her, it again blacked the screen before returning to the home screen. I have cycled the power on the watch with no change. Any other suggestions?
