Don’t. Don’t install Google spyware on your phone and don’t give this garbage company even a fraction of a cent. Also, stop pretending that it’s impossible to block ads on YouTube, there are many ways to do it: There are web clients like Piped and Invidious, there is FreeTube for Desktop and on Android you can use LibreTube (client for Piped), NewPipe, NewPipe x SponsorBlock, it also has Return YouTube Dislike built in, or Grayjay. On iOS, you can use Yattee, just follow this guide to set it up, it should also work on the Apple TV if I’m not mistaken, or just add the Piped website to your homescreen. If you have a device that runs Android TV, you can use SmartTubeNext.
