Just started with my 220+ and have the audio station app on my iPhone which does fine on my home network. I noticed the audio station came up on my CarPlay (Chevy) and was real excited to be able to access my tunes in the truck... but when I open the app in CarPlay it spins... tryin to access.... nothing. Any place to start the diagnostic steps would be appreciated. I have not gone to DMS 7 but otherwise all up to date.
