Hello. I have some issue to understand the compatibility between Adguard and a VPN that belongs to the compatibility list. When activated Adguard is dealing with the DNS requests. However when activated the VPN creates a secure tunnel where DNS requests should go through. If the DNS requests don't go through the VPN tunnel then we will have a DNS leak with an impact on privacy and anonymity. So what does the compatibility means exactly? And how requests are managed between Adguard and the VPN? How really secure is the connection? Thanks for the explanation.
