Issue Details

Steps to reproduce:

1. Turn off Adguard Dns filter (Optimised) only.
2. Dns server should come by default Adguard dns non filtering.
   3.need to optimise Adguard Filter (Optimized) so that it can't blocked internet access

Expected Behavior

No response

Actual Behavior

Blocked Internet access when under DNS protection then DNS filters>Adguard DNS Filter (Optimized) is toggle on, even if you use any DNS like Automatic, Adguard DNS, or Public DNS.

*Cause of this issue: When mobile data or WiFi is on and we are accessing internet and Adguard is on than it works fine without any issue, But when we turn off Mobile Data or WiFi but Adguard is on in background because we are now not using internet, but when we need to access internet then we on mobile data or WiFi, then it block internet access.

Solution which i use: 1. Restart your device.
2. Turn off Adguard DNS Filter (Optimised) only, there is no problem of we use Adguard Dns, Non filtering or even Public DNS.

Suggestion: I don't think Adguard DNS filter (Optimised) comes Toggle ON by default because Adguard also mentioned that it cause Problems depending on your Adblock or specific websites. Or we need to optimised so that it can't blocked internet access.
