Just telling you about my experiences of sleepwalking. I'd love to know if you sleepwalk, let me know either in a comment or a video! Thanks for listening, commenting and subscribing!
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
