So basically you rebuild the YouTube app using revanced manager.
- Make sure you nuke YouTube from your phone.
- Download YouTube apk from apkmirror (don't install yet)
- Download and install from revanced.app
- Patcher -> select the YT apk. Patch as recommended and install
- Download, install and login from microG.org (basically an emulator for Google play services)
- ???
- Realise you can do the same for ad-free R*ddit, twitter, Instagram apps
