I have YouTube Premium though not the Family variant and Google won't just fix their app. It is way behind NewPipe or YouTube ReVanced. No, I don't need shorts. No I don't need constant nudges to join groups of YouTubers by paying after I just paid you money, Google!
What I want is system wide quality setting (what exactly does High or Data Saver mean; would it kill you to give 480p, 720p or 1080p as options) or Sponserblock integration (okay, this thing is probably never gonna happen but still). YouTube 's app is a stinking pile of shit. I just use YouTube Music from them and will cancel/not renew my plan after it lapses.
Not a premium user but Youtube has poisoned its own waters with its algorithm. You can see the "top" content basically gaming that algorithm as well as it can. Literally every part of it from the title to the thumbnail to the content itself is hollow except for the skinner box.
It's funny, because sponsorblock and vanced only exist because of youtube's greed. And now I can't imagine using their service without them, even if they rollback the annoying ads. And they can't implement them. It's really the problem they made for themselves.
