Family rules do not prevent phone use on Samsung A3 Android 8
Family rules (bedtime etc.) do not seem to prevent phone use. My kid's phone shows only a notification (f-secure logo and piece of text in the android status bar/notification drawer) about Family rules and bedtime, but they do not prevent phone or application use.
The phone is a Samsung A3 (2017) with Android 8.0.0
I have tried reinstalling SAFE, restarting phone, and even re-installing/recovering everything due to unrelated phone maintenance.
Is there some setting outside the SAFE-app that prevents correct operation?
