I'm trying to install Sonos One. When trying to connect the controller to the speaker, I get the message Version Unconfirmed. 'There was a problem confirming if your Sonos Controller is up-to-date some features may not work'



I can then go on to connect the wifi successfully, and can use the music function with streaming etc, but the setup does not give me the opportunity to either configure the optimum speaker setup or to enable Alexa. Have tried on two different PCs, one running windows seven and one windows 10 as well as a android phone, same error. Have tried unplugging and resetting router, same error. I've noticed this 'up to date' problem seems to be common but have not found any solution. Any advice?
