We've got a (paid) spotify family account and I have set up spotifyd with my user. However with this, my son could not 'respot' to spotifyd (but he could see the device in his official spotify android app). Is this the expected behaviour? Is there a way around?

BTW, there a 'dump' devices like speakers that spotify could 'respot' to that are not registered/associated with a spotify account. I wonder if there is way to run spotifyd in a similiar mode?
