@AppleSupport new update sucks. I think there’s a bug issue with @YouTube - when I’m playing music on YouTube i.e. walking or playing my tunes while someone is driving, it cuts off and pauses the music when I haven’t even touched my phone! Please fix or look into this glitch.
That's definitely odd behavior! Try these steps: delete the app > restart your device > reinstall the app. Let us know if that clears things up.
