Hi ​@EdK, welcome to the Sonos Community!

I’m sorry to hear that you’re having issues adding SiriusXM to the queue.

I’m not able to test this service myself as it’s not available in my region, but I’ve tried with a few other services and still have the option to add to the end of the queue. This option does only show up when something else is in the queue, so make sure you’re playing something first, then try add a second selection to the queue.

If you aren’t seeing the option while something is playing, check if the Sonos app is up-to-date; you may need to check your app store in case the app hasn’t automatically updated. 

I hope this helps, but if not, then please reach out to our support team for further troubleshooting, as they have the necessary tools available to help you resolve this.

Thanks Jamie.  After a few failed attempts, I shut everything down, restarted and that functionality is back.  You are correct that it is slightly different in The new app in that it requires you to play the first selection before building the que.
