I have Norton Family installed on both of my children's phones. I keep having issues where it stops working--it will show they have not used their phones when I know they have, or show that they are still in a location that they left hours or days before. I also stop getting alerts from that device. Sometimes restarting the phone helps, but why does this keep happening? I would like to have continuous monitoring without interruption. My oldest son will start driving soon and I would like to be able to know where he is! Thank you.
