Hi, I'm experiencing the exact same problem using latest FTL branch version :
Pi-hole Version vDev (FTLDNS, v3.3.1-85-g2e6a937) Web Interface Version vDev (FTLDNS, v3.2.1-179-g3fd9b4d6) FTL Version vDev (FTLDNS, vDev-dbd039b)
I have no IPv6 CIDR notation in /etc/pihole/setupVars.conf (no "/..." after IPv6), IPv4 address is suffixed with /24, I tried to remove it and restart FTL service, but still the same problem.
Here's a look at what appears in query log with blocklisted domain "settings-win.data.microsoft.com"
And using dig in CLI and another blocklisted domain, for "A" type queries the IP of the PiHole is returned as expected, but AAAA queries aren't blocked :
➜ pi > dig -t A googleads.g.doubleclick.net
; <<>> DiG 9.10.3-P4-Raspbian <<>> -t A googleads.g.doubleclick.net
