Norton Family seems to work---partially

We have Norton Family set up for 3 children- 5 devices.  The 3 cellphones (2 Android, 1 iphone) are the main concerns.  I can see that the devices are being monitored, and often get "website blocked" notifications, but the time limits are not working (text history shows texts being sent well after 10 pm) and Time Supervision shows no activity in the last 7 days, when I know for a fact there is activity.
