Doesn’t work here. I started getting this a few days ago, and they don’t appear on every video. But right after I applied this solution, killed all the Chrome processes and reopened the browser, the very first video I started popped it up on me.

Edit: Just downloaded FreeTube. You got a choice, Google: you can stop bothering me about adblocking and continue to collect data on me through YouTube, or I’ll use something else, and you get nothing. Either way, I’m only going to consume content that I want to consume. That includes a lot of ad rolls that creators do themselves; lots of people make those entertaining to watch, and I watch those. And creator ad rolls don’t just cut in randomly in the middle of a sentence. They match the tone and appearance of the rest of the video. They don’t completely break continuity.
