As of the last/latest update, 95% of the time when I plug my phone to use Spotify, it automatically plays music to the rear speakers only, as if I'm using the Google assistant, (the Google voice becomes the default, not the stereo volume). I found a work around, but it's annoying. I have to ask Google for a location, once it calls out the first direction the front speakers start to play music. '18 Subaru Crosstrek, S21 Ultra phone. Never really had this issue till the last update.
