Issue: On some sites, filtering fails to work when mobile data is set to use IPv6 (or IPv4/IPv6 and the ISP uses the latter). The cert issuer remains original and ads aren't blocked. Again, I can't reproduce this on all sites, for example Google and Wikipedia is filtered. Https filtering is active and high quality mode enabled. Workaround: Setting access point to IPv4 does not cause this issue and ads are properly filtered; the cert issuer is Adguard. Device and OS: OnePlus 5 running Android Pie. Browser: Chrome on Android Adguard Version: Latest Beta v3.0.297, also happened on older versions (v2). I took screenshots of some sites when this happens, both when using IPv4 and IPv6.
