Since yesterday, if we tell Alexa to 'play realjazz on SiriusXM,' she responds with 'playing realjazz on SiriusXM' but no music ever starts. If you start the music through the app using her as a zone, it plays, but if you say 'Alexa shut up' she doesn't stop the music as usual. It seems the Sonos functionality of Alexa is tweaked somehow. Other non-Sonos functionality of Alexa seems fine, like if I ask her to tell me a joke or the weather, she does so joyfully.
How can I fix this?
