While using Adguard with Norton VPN using split tunnel, Adguard DNS protection could block all domains specified. However while using Surfshark with Adguard, none of the domains are blocked for the obvious reason that Adguard DNS Protection is switched off by Surfshark. While using Norton VPN, Adguard configuarataion stays under VPN Configuarations while Norton comes under Personal VPN. However Surfshark installs a UDP connection under VPN Configuarations which replaces Adguard, along with another VPN under Personal VPN. Why is this? This is for iOS and iPad OS only.
