Hello Flood, thank you for looking into my issue here. Version for KTS is 21.2.16.590(b) and extension is 1.3.8.0. Hello Igor, thank you for looking into it as well. Yes, i meant Anti-Banner. Add is the first thumbnail on the below screenshot…, whilst on the right you can see that Anti-Banner is enabled and it blocked zero adds. It let other adds slip in when video is being played. it is strange as sometimes it does work and sometimes it doesnt… thank you both for your help!
