My Question or Issue

Hi!
I Work at Oslo Hi-Fi Center, and we have lots of different speacers, amps and other equipment with spotify connetct. 

on all other devices i've tried Spotify connect works, but on my Note9 phone i only find the ones that are "Google cast" and the demo Bose650 system, this is also logged in with my account so i guess thats why it appares and not the other ones. 

Any suggestions? i have of course tried to uninstall the app and install it. spotify, my phone, the speakers and the routers are up to date.
