You’re an anti UI extremist like me, you’ve selected « hide all UI » in the settings and yet you see that the useless radio UI is still there.

Don’t worry.
Simply go to your regular menu then to your phone menu then select your radio/podcastsmusic app. Then delete everything on your playlist. The radio UI will disappear
