It blocks the YT ads. Watch video, cast to TV. Isn’t that what your original question was? I mentioned SmartTube in my 1st reply as it’s the best adblocked YT experience on a TV for sure, but it does require an Android based set top box or TV OS. If you are in an Apple ecosystem, use brave just for casting YT to TV.
