I use radio mode a lot. For a long time, it would at random times get “stuck,” in that I would not press pause but it would stop progressing. This has happened with much greater frequency the last few days to the point where it’s happening over and over. I have to quit the app and restart to get it going again, it works fine for a while (sometimes not very long), and then gets stuck again.
I’m on iOS 18.5.
