Bought the SONOS system on recommendation however I live in Western Isles of Scotland and the Internet connection is not the best. We bought the connect amp along with 2 x 3 play speakers. and 2 tannoy speakers for for our bar to give us some umph on party nights. Before I was using a Bluetooth connection from downloaded content via Spotify that was great. Now it seems to be on the whim of the connection, even though the content on spotify has been downloaded. When our connection goes down SONOS doesn't like it one bit, even though our spotify content has been downloaded! What's the solution?
