Firewall not working on rooted LineageOS even with Take Highest Priority enabled

Firewall is not working on LineageOS (on my Moto G2 - thea), even with Take Highest Priority enabled.

It doesn’t stop any app from accessing the internet.

I get the Avast Mobile Security is granted SuperUser rights notification when I open apps I blocked with Avast’s firewall.

I need LineageOS to get the latest android updates, so it would be great if you could get it working!

(PS: How I got root on LineageOS: Root is not baked into LineageOS, you have to flash either open source: LineageOS’s superuser https://download.lineageos.org/extras, Magisk http://tiny.cc/latestmagisk, or phh’s SuperUser https://superuser.phh.me/superuser.zip, or closed source: SuperSU http://www.supersu.com/download which has a weird zygote bug - zygote asks for root permission which is should never do - on my device and was controversially sold to a Chinese company: https://www.reddit.com/r/Android/comments/54xdmp/ccmt_who_exactly_are_the_owners_of_supersu/. I am using Magisk’s open source root with Magisk Manager installed which is the best root for my device and works perfectly. Just Avast Firewall isn’t working which Avast can hopefully fix! (to potentially help someone - I got Magisk working on thea by flashing Magisk immediately after Gapps, after first flashing LineageOS. You then need to install Magisk manager from the Play Store. As of 24/2/17, enabling Magisk Hide can’t pass SafetyNet due to it detecting unlocked bootloader which you can’t relock with a custom rom without soft bricking your device, so you can’t use Android Pay, but it lets Pokemon Go work).)

Thanks!

Hi, unfortunately I do not know how exactly this modifies the ROM, or how to help you. The thing is, the functionality on a customized Android can never be 100% guaranteed.
