Hello, I have such a problem. Previously, I had pihole 5.0 installed on raspberry pi 4 and everything was OK.
Now I installed pihole on Raspberry pi zero and here everything seems to be ok in the log, I see that different devices connect and pihole blocks unwanted sites. However, in the network tab I don't see any device using pihole. Why is this happening earlier on RPI4 everything was fine.
It has been running for several hours and nothing appears, unless it needs even more time (I think that the RPI4 devices appeared immediately.)
Result of the command

Was the device active recently? I think they must be on (and actively doing requests) so Pi-hole can pick them up. Also, do you use the DHCP server of your router or the one provided by Pi-hole? If former, did you specify your router as conditional forwarding target?
devices are active all the time and send queries. I am using the DHCP server provided by pihole. I did not specify the router as a conditional purpose of provisioning - how should it be done ??
