Since last week, Spotify connect stopped working. My AV Receiver is visible as an available device, but I can't assign it to stream music neither from my Win10 computer or from my Android 8.0 phone, or my Android 7.x tablet.
Tried downgrading to the previous version for windows, x.72.x but that did not help.
We've merged all the issues about multiple receivers not working, since Spotify is no longer supporting them. You can find a full list of all the speakers we no longer supporthere.
Don't hesitate to open a new thread if anything else comes up.
