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.
If you are on Android, use RedReader. It still works with full functionality as before, except that NSFW subs can’t be opened. It’s available on F Droid as well.
