Hi @Gene660515
Welcome to community.
To clarify, as a free ad supported listener, Pandora beginning to play when the app is launched is an intended experience. Plus and Premium subscribers have more control over initiating playback when opening the Pandora app.
For your experience connecting to Bluetooth devices. If Pandora was the last music source that was playing it may automatically resume when reconnecting.
You can disable this functionality with the following steps:
Open Pandora.
Tap Profile.
Next select the Settings gear in the upper right corner.
Tap Advanced.
Under Bluetooth for devices uncheck the box next to Launch from car.
