That’s Vanced. ReVanced is a new thing where you take the official YouTube APK(or some other apps)and patch it yourself. They have an app that does the hard work for you. You just have to find an APK for the right version of YouTube via APK Mirror or similar.

I don’t think so? Vanced was but I’m using ReVanced just fine. Unless it’s recent-ish news I missed out on?
