My buddy reported that he started getting blocked using uBlock starting today.
I've never had any of the problems, but I have some caveats that may be helpful:
I live in Korea
I use brave browser with no uBlock as it's unnecessary
I also use NextDNS at the router level.
#3 seems to be of no consequence as I tried using vanilla Chrome and ads played while randomly testing videos
That leads me to believe #2 or #1 is preventing ads.
I didn't disable NextDNS since it failed at #3, and I haven't tried VPNing into a U.S. endpoint out of laziness.
Either #1, or #2 is preventing ads ... I'm inclined to believe it is #2, Brave browser, that is successfully blocking ads; even without VPN, with NextDNS, I was still getting ads in vanilla Chrome.
I think there is something in Brave browser that is currently overlooked.
