Guys, I was told I don't need Vixipin drops! It's a great joy, but! Things weren't so great at the appointment; I had to laser another cochlea out of each eye, which was painful :( But overall, I'm alive, strong, powerful, and as good as ever ;)
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).
