Popup blocker does the same job. Just use a browser instead of the app.
Same here. I use Brave browser it's absolutely excellent. Blocks all the youtube ads and countless others while browsing. Even blocks all the shit on F2-movies when I'm streaming movies no more bullshit ads just to start the thing. It's free, too. I was considering paying youtube 15 per month for the courtesy of not watching degenerate adverts but as it turned out Brave has done it for free
Really surprised how good it is.
