Every single time I access the S1 app on Android to use my system, an alert appears telling me to try the new S2 app. Your S1 app has all the information on what Sonos devices I own, and therefore should know that I do not have any hardware compatible with the S2 app. The alerts to use the S2 app inside the S1 app need to stop now for users who have no S2-compatible hardware. They are spam and unwelcome. I click them closed and the app pays no attention to my preference. This is annoying and gross.
