My Question or Issue

As above I have the free version,  just bought a new car and via bluetooth i have very low volume. Increased app volume, and check spotify settings under playback. There are no options available under play back to increase volume.

At full volume on the car radio it is a fraction of the volume I get on the radio.

Simple advice please as 68 years old with limited computer skills 

Thanks in advance.
