My Question or Issue

I just got a new car, Hyundai i20 2021 version, which has wireless Android Auto.  Unfortunately Spotify won't work.  I can open it and select a track but nothing plays, even if the track is downloaded to the phone.  I have tried various solutions such as clearing the cache, rebooting the phone, reinstalling Spotify, removing optimisation for Spotify but nothing works. Any suggestions would be welcome, thanks.

I've worked out that this is because my phone is connected to the car Wi-Fi and Spotify is trying to access the internet through this but it does not have internet access.  Blocking Spotify from accessing Wi-Fi solved this but i need to figure out a way of blocking only the car Wi-Fi.

Just turn off your phone wifi and leave phone network on

The whole point is to connect to Android Auto wirelessly, switching off Wi-Fi prevents this.
