Nothing, it works just fine for now for me too. I'd still recommand an open source app called NewPipe over YouTube on FireFox, it seems way less hungry battery-wise... and there is likely also less data collection happening.
But I definitely also recommend trying out frontends that support it.
I cannot imagine trying to use video while having to run a gauntlet of both YouTube ads and video sponsor segments.
