I install the app for pandora music and comes on when I first start it up and plays fine , and when shut it off and start again it dos’nt come on , on till later on .
I don’t understand your description of the problem. I’d suggest reading your owners manual first and then visiting the dealer with this question if the manual doesn’t solve it.
I know what you mean. Pandora is tricky. My only suggestion would be to check that your app on the phone is up to date. You can also run it via BlueTooth if you choose. This happens on a lot of cars I test.
