Modded version of youtube app that let’s you kill all the ads, among many other wonderful features. However, every 6 months or so, youtube does something where the videos stop loading effectively killing the app. I usually switch between vanced and revanced every 6 or so months because one has so far always worked when the other gets the axe. By the time that one goes down, the other one is back up and running.
Sounds like your friend is just some dumbass who’s trying to fit something in there that just doesn’t. …that’s what she said
