Pi-Hole Troubleshooting

I have PH installed on my FW Blue.  Install went perfectly other than message at start that I did not have admin cred.

I changed the IP address for the DNS server as indicated in instructions.  Everythign seems to be operating just fine in terms of web access for all devices.  Web interface for PH works just fine. FW dashboard all looks good.

However, it does not appear that PH is blocking anything.  PH dashboard says it has not blocked a single query or ad.  If i turn off FW Adblock and go to an ad test site, it appears that there is no blocking at all.

any suggestions as to what i can troubleshoot?  

I am running in DHCP mode b/c my router is a google mesh wifi.  Secondary DNS is changes to the FW primary IP.  Family mode in FW is off.
