Yesterday I opened my Sonos app (S 2) on my iPhone to play some music.
Instead of the normal screen, I had a message to the effect that “an update is required before app is usable.”
I have automatic updates turned off in system settings, and prefer to manually update to a new version in case of bug(s) being discovered, etc.. I have never seen a message like this before, and would prefer to not be forced to update.
I am now updated to S2 16.5.1 (build 82360160).
Please advise as to (1) why this happened and (2) how or if I can avoid being forced to update in the future.
