Switching to Sirius from CarPlay

Yesterday, while driving home, we wanted to switch off of Audible on CarPlay to Sirius. But while my husband was able to get off the CarPlay to the Sirius favorites display, we couldnt get it to actually start playing.

Is there a trick to that, short of unplugging the phone from CarPlay? Known problem? Typical Mazda Connect bug?
 
I just recently installed CarPlay on my 16, but I had the Sirius app previously installed on my iPhone. You should be able to switch to that within CarPlay itself. I also believe you can push home button or go to the Mazda icon app in CarPlay and choose audio sources possibly.
 
You should be able to push and hold the home button for a few seconds, to switch between CarPlay and Mazda interface. This is what I do to play the radio while using apple maps, nice thing is I can just push nav button and it will take me directly to apple maps.
