For the past few months Sonos is requesting that I approve their Terms and Conditions nearly every week on my Mac. Sometimes more than once a week. If I have open applications open (which is usual) and the request becomes hidden behind other pages my Mac is frozen until I respond-which I can't as I can't get to the approval page. In these cases I must force quit Sonos and restart the app to free my machine. Why am I getting requests for approval this frequently and why is it freezing my entire machine until I respond? Is there is way to avoid this problem?
