My Question or Issue

I can no longer ask Siri to play a playlist — this has stopped working only in the last week or so.

I used to be able to say "Play my Blah playlist on Spotify", and it would play as expected. Now Siri just says "Sorry, there was a problem with the app." — see attached screenshot (and yes, this playlist obviously exists, and yes it plays fine otherwise).

Note: if I ask Siri to play an artist, this still works as expected. Screenshot also attached sahowing this.

I'm running the latest iOS and Spotify updates (version numbers provided above) on a new iPhone 11.
