My Question or Issue

 I have experienced on any iPhone devices and with carplay on a really low volume on the car, this doesn’t happens with Apple Music, iTunes, or any other app, just with Spotify

if I use Bluetooth I can hear perfectly the song at 15 but with CarPlay I need to take the volume to the top at 45 at not even can hear it well

several persons are reporting this and no fix has been released from Spotify any ideas how to solve this or pass this bug to the developers??? Because Spotify isn’t working correctly while in CarPlay mode

I have had an issue where the sound from Spotify, when plugged into USB in the car, the sound only comes out of one speaker (like when you access/interact w Siri). I haven't tried this yet, but believe it will be the cause and solution. It has to do with "Hey Spotify" feature....that has never been used by anyone...but now causes issues. Hope it works for ya.
