I use this fork https://github.com/polymorphicshade/NewPipe It removes ads from videos
I've just started using New Pipe video app for YouTube. It removes all the advertising, like if you had premium. It's brilliant 😃

It does not use any Google framework libraries, or the YouTube API. It only parses the website in order to gain the information it needs. Therefore this app can be used on devices without Google Services installed. Also, you don't need a YouTube account to use NewPipe, and it's FLOSS.
