Spotify not working

[Twistedrose1993]

I have a iPhone 6s Plus and for some reason within the last 2 weeks ever time I get into my car and the Bluetooth connects Spotify will flash and lock up and will not play music nor give me an option to choose a song. I’ve tried reinstalling, rebooting my phone disconnecting my battery on my car and resetting my stereo. Any help at all? This is really bugging me driving to work with no music on an app I pay for but can’t use at all.
