I'm having the same problem but I don't see the solution on my profile options. Are you talking about "Enable Auto Start"? That's turned on. I've had Pandora Plus for years and this problem started a few months ago. When the phone is locked it will play one song and stop. This happens whether on wifi or data. If the phone is open it will keep playing. My Android version is 12 and I've gone through ever troubleshooting step including background battery etc. I've updated the app. Cleared the data. I'm at a loss at this point.
