Expected Behaviour:
Clients are connected to Pi-Hole and blocking is successful.
Actual Behaviour:
Clients are connected to Pi-Hole and and Pi-Hole shows that Querys get blocked, but there's is no visible blocking of ads whatsoever. I've got about 200.000 domains on my blocklists, use a DNS upstream server which also filters malware itself (which it didn't) and all of my devices have Pi-Hole as their DNS server.
