Samsung s8 firewall

On my s8 even with the fire enabled it fails to block any apps, netgaurd doesn’t have this problem and function correctly but sometimes just stops everything thus me looking to switch.

The app looks great but I really do need the firewall to work any ideas?

ok so ads have stopped showing in es file manager which makes me believe that it is intermittently working which is great. Still shows network actively even on blocked apps? is this normal behaviour ?
