Issue Details

Steps to reproduce:

1. Enable Automatic Proxy routing.
2. Enable DNS filtering with Cloudflare DNS.
3. Turn off Wifi and switch to mobile data.

Expected Behavior

AdGuard DNS continues to function and DNS lookups appear in recent activity. Visiting https://1.1.1.1/help should indicate that Cloudflare DoH.

Actual Behavior

AdGuard DNS filtering is no longer functional and DNS lookups do not appear in recent activity. Visiting https://1.1.1.1/help indicates that the device is using the carrier's IPv6 DNS address.

Additional Information

This is likely related to #4976 - Automatic Proxy functions on wifi and completely fails when switching over to mobile data. I believe it may be related to the fact that T-Mobile is only IPv6. VPN routing works pretty well, however my impression for when I purchased the $80 license was that I would be able to use root instead of VPN. After spending 12 hours fighting this problem, it appears to not be the case.

Is there any workaround for the carrier hijacking the DNS?
