I find the autoplay so annoying because it hides the thumbnail which was carefully designed to communicate why I should click on the video and replaces it with, usually, a talking head or stock footage. Often the video gets inexplicably added to my watch history, and if I do choose to click on it I have to go back to the beginning because I missed the start of the audio
Additionally there's a bug on the Android app that it sometimes doesn't show video titles (or the worlds worst A/B test?), so scrolling through I just see talking heads (since it autoplays instead of showing the video thumb) and have to force restart it to actually understand what's going on.
As a counterpoint I love that feature on desktop and use it all the time.
Often I don't even click videos but just watch them with the preview autoplay (with sound enabled). I also zoom in on my mousepad so that it covers the whole screen and I only need to click through to like the video or for the comments. Much more seemless experience for me.
