I have a free plan on spotify with an apple watch series 3, iPhone XR all on the latest update. My car has been playing spotify wirelessly via bluetooth just fine up until recently when all of a sudden it now will not play. The sound comes through my phone instead even though the car's screen shows the song information. I figured out when I turn the bluetooth off to my watch, it plays through the car. How do I prevent this from happening so I do not have to turn my watch bluetooth off every time?
