@TeamYouTube I have YouTube Premium and background play enabled. Everytime I turn my phone screen off, the video stops playing and I get an explanation point in my notification next to the video. It's only a specific video. It works on other videos. Samsung Galaxy S9+ app up2date
Thanks for trying those steps. We recommend reaching out to our YouTube Premium Support team. Here's how: http://yt.be/help/mnQE . They can look into the details and help you further. Hope this gets resolved.
