Just a suggestion to offer the option of a push notification to system-linked smartphones/devices when a speaker starts playing via voice control (Alexa/Google). The notification would ask if the phone should open the app to allow control through the smartphone/device.
I often start playing music on my Sonos One through Alexa and want to make volume/pairing adjustments through the Sonos app. If there was a notification on my phone ready to tap and make adjustments it would the whole process smoother and more integrated.
Many thanks.
