Vanced died after they got a cease and desist from YouTube. You might want to recommend https://revanced.app/ instead, which patches the YouTube APK directly on your phone instead of distributing an APK with modified bytecode (which is the given “reason” YouTube killed Vanced)

ReVanced also has patches to remove ads/crack features for other apps as well, which is an added bonus. They’re also open-source
