Pi-hole is amazing, but before standing one up, be aware that it does not block YouTube ads without additional configuration.

I agree, but to anyone considering setting up Pi-Hole make sure that you don't go "overboard" with blocklists. I did and ended up blocking too much, to where regular Instagram posts, post messages, etc. were removed. It also slowed down my internet considerably, but that could be due to the excessive blocking.

We ended up uninstalling Pi-Hole and removing it from our network, which was a pain in the neck. I remember that simply removing the blocklists wasn't enough to undo the damage, which is why we had to go with the removal from network route.

I've considered revisiting Pi-Hole in the future, and I'd definitely be more cautious that time around.

With pihole I keep getting playback error when video starts basically cause the ad can't play. If I refresh then it plays normally cause YouTube doesn't show the ad the 2nd time being tricked it was already watched.

As far as I know you cannot install adblockers on the Android app for YouTube for example, and probably on other platforms too. I've looked for one but found none.
