I’ve used it on my Android TV. Definitely could work better for that, but it’s usable imo

Findroid may work better?

Right, that makes sense if you can’t adjust your router’s DNS. However, you can manually change the IP address of the DNS servers you want to use per device. I recommend trying to change the DNS on your computer or something to your pi-hole’s IP address. If you do that and can get internet access you should be good. If not then you can check the pi-hole logs to see if it’s getting any of the DNS queries. Feel free to DM me for more help.

If you set the dns address manually for a device instead of relying on DHCP does dns work then? That should work fine no matter what your router is giving out.

So to clarify, what are you wanting to happen and what is happening instead?

This was my recommendation too. Simplest setup you could ask for to create a VPN connection between devices with wireguard as the base.
