I have a question: do you need to select ‘Spotify’ in the wtx-microstream app, and only then you can connect from Spotify to this device? Or once it is setup, can you always connect from Spotify just like that? And what about my family members? Do they all need the wtx-microstream app installed on their phones? Will that work? Or can only 1 person have the app installed and connected? Or is wtx-microstream simply visible in Spotify (with a premium account) for everyone in the same WiFi network?
