Hi @MichaelAJ, thank you for reaching out to us, and welcome to the Sonos Community. I appreciate you for providing us with a detailed concern. Let me help you and figure out what's happening.
First I'd like to ask questions to isolate the issue so we can create a path towards resolution.
- Do you experience the same on your other music services?
- Have you tried removing and re-adding SiriusXM on the Sonos app?
You may check all your settings to make sure the cloud is syncing in the SiriusXM account (SiriusXM pushes what is displayed on Sonos) it depends on the music service how it's being shared to us.
After checking the steps above and you're still having the same issue, please submit a diagnostic report to further check on this and provide the confirmation number in your response. Let us know how it goes. We'll wait for your reply.
