the blocking for the internet access does not work. I touch the OFF button in Firewall, I accept all, but I still see the OFF button, so the firewall is not turned on.
I am able to select apps or better said to restrict their data (data icons are crossed), but when I turn them on, they connect to the internet without any problems.
I am using Android 10 and NordVPN.
update: I have deleted (in Android settings) a VPN profile for NordVPN and the firewall started to work, when I recreated it, the firewall is off. So I suppose there is a clash between those two. Is there any way how to get them to play along?
