Haven’t done it recently in iOS 13, but I had this issue in iOS 12. In my case, I was running the shortcut from the widget and it would crash. I added a step to run the shortcut in the shortcuts app itself which cleared the issues. In my case, it sounds like an issue with RAM allocated to the widget which my workaround solved.
Baffled by this issue. Continue in Shortcuts didn’t work. The shortcut just kept resuming playback rather than changing playlists. So, I quit Shortcuts and Music, and then it worked.
@sylumer I’ve had this issue for ages—pretty sure I’ve force-quit Shortcuts/Music before only to have it come back.
@motopascyyy Sure! I’ve seen it fail on every “Play Playlist” action I can think of, though, so this Shortcut isn’t particularly exemplary.
If you like electronic music/Deadmau5, you might like the Shortcut anyway. It randomly selects one of the 12 episodes of the Mau5trap radio show playlists and starts it at the beginning. (I assume a shared Shortcut preserves the chosen playlist in “Play Playlist,” but I did select these from my library, so it’s possible each Play Playlist will just turn out blank.
