I've checked that my router continues to point to the pihole (no fallbacks, though I've tried with fallbacks and no difference). I also setup the pihole with cloudflare. I'm just always confused because it seems like some people have absolutely no problem and there's others in my camp and the former just stop after "just follow the directions." I even remember the LTT video mentioned this specific problem.

I went down a similar rabbit hole recently with unbound as a caching resolver, where it appeared to work on my real computers but didn't on phones. I took a pcap and found that my Android 10+ devices were refusing to use the good-old port 53 DNS my unbound jail was serving because it wasn't DoT. Once I set up unbound with real certs _and_ set it as each device's "Private DNS", it worked as expected.

Your issue might be different but I suggest taking a pcap to make sure your assumptions about what is answering a given DNS query are true.

Oh I didn't realise anyone had that work. I just assumed it wasn't possible (i.e. ads served from same domain as content) and uBO was able to do it by 'content blocking' (i.e. DOM manipulation) rather than XHR blocking.

So, you're not alone, me too.
