That’s BS. It’s impossible for something like pihole to block ads like the ones we get on YouTube/Android tv because they are served from the same domain as the regular content and a pihole doesn’t know the difference.
The only way to block them is to run unofficial apps that replace YouTube and the likes.
I really don’t believe it. At some point it was even a suggested workaround to intercept requests to port 53 because the Shield or its apps were not honoring your network’s DNS configuration. Which would be similar to the pihole not being in the picture at all.
If it’s really working for you, I suggest telling the community how you’ve done it because this question pops up every other day and the answer is always the same.
