God I hate shorts. Luckily you can disable them. But youtube is so riddled with ads in general, it makes watching without adblock impossible. If they'd go back to one 3 second ad at the very beginning, I might even tolerate it. But the current shitshow? Not on my system.
Doesn't help that they have a whooping 113 trackers running simultaneously.
None of those apps are the original and official app. Which is pretty obviously what this was about. I used to use Vanced and it never worked as easily as everyone seems to imply, and I never could get it to cast. Vanced is no longer available on the PlayStore btw, and the same can be expected for every app that tries to offer YouTube content, modified.
