I have been with pandora for years and have not had to pay for the service. Why is it making that a mandatory thing now?
Welcome to community!
A subscription isn't necessary to listen to the Pandora app on your mobile device or when connected in your vehicle.
Can you tell me more about your experience? Checking your Pandora account I don't see any associated devices. Are you having trouble installing the Pandora app from the App Store on your mobile?
