I have bought a Sonos 1 for voice control with Alexa. I already have 4 Sonos 5's. I have uploaded the Alexa app and added the sonos skill and it has discovered all the sonos devices but when I ask Alexa to play anything she tells me that I need the Sonos Skill. I have disabled and enables the sonos skill but Alexa will not recognise it. Is this a UK problem?
