But, it's got my one 'killer' feature YouTube doesn't have: Background play. And that's enough for me.
Also, I have numerous YT alternative apps installed, plus official YT app, so if I need any of the missing features, then I use one of the other apps that has it. And begrudgingly fall back to official YT when all else fails.
That's why I point it out as a missing feature: It's so basic, and yet it's "premium". I'm also intentionally separating YouTube from YouTube Premium* in terms of features, in which context YouTube is missing the background play feature.
*It may be the same app that you open, but the features are distinctly different, so I treat them as separate apps in my mental model. I would do the same for Spotify, for example.
