This app is terrible as it constantly tells me my daughter is offline and does not track PROPERLY at all. I have tried to uninstall and reinstall as suggested. We have checked all the permissions and mobile data is on etc but does not work for longer than an hour at most. Even if the phone is right next to us with excellent signal it still doesn't pick it up. NOT WORTH PAYING FOR!!! Update we are still having the same problems and the agents do nothing to help as everything fails. AVOID
