An APK backup of YouTube Vanced.
YouTube Vanced was a modified third-party YouTube application for Android with a built-in adblocker. Other features of the app included a sponsor blocker, background play, free picture-in-picture, an AMOLED black theme, swipe control for brightness and volume, and the ability to restore dislike counts on YouTube videos.

YouTube Vanced was discontinued because of legal reasons so I am making a backup of the APK's. These APK's should work for 2 or more years according to Vanced Official. Vanced MicroG is necessary for the other apps to work.
Vanced Manager : GitHub or Mega
YouTube Vanced : GitHub or Mega (It's an apkm file so you will need https://www.apkmirror.com/apk/apkmirror/apkmirror-installer-official/) (Also it's the normal dark mode edition, not the black edition.)
YouTube Music Vanced : GitHub or Mega
Vanced Manager should still be working, so you may not need to install the other apps. This is because although the main api url is down, there is a backup api that the manager switches to.
