I tried again and again all of the stuff you mentioned in this topic but nothing worked even now if I reload the page, ads come again… Not only banner ads but pre roll ads as well…
I have tried only https://www.speedtest.net/ which in chrome gives so many banner ads but they are still blocked in brave…
But for YouTube ads come and not even once or twice I tried to click videos one after another and I got ad on each of the video…
More information in the next reply
I clicked randomly on any video and as you can see in the miniplayer in the screenshots below, each of them played a pre roll ad. Even the banner ad stayed there for the whole time.
