I have had two Sonos One SL speakers for ages that work fine. Today I tried to connect a new third Sonos One SL speaker. I did the updates etc but it says this error for the new speaker: "Incompatible Software Versions. The version of the app you're using isn't compatible with your Sonos system, so some settings have been disabled".
Please can someone tell me a simple and quick fix for this please. Thank you
