I just cleared the YT sites’ cookies, relogged in and it disappeared. I use AdNauseam and uBlock Origin and still got this.

If they weren’t so intrusive with the garbage ads (I hate publicity, over 95% of it is condescending and/or lies), I wouldn’t mind seeing an ad in the beggining, or even also an additional in the middle of a long video, but getting two unskippable ads in the beggining and one every 5 mins or less is abusive. So fuck you Google.
