you can force a firmware update by resetting the Soundbar 700 to factory default and running through the setup again. Greetings from Holland
On the remote, touch and hold the Power button and the Skip Forward button
The soundbar will reboot. When the reset is complete, the light bar will glow solid amber.
Open the Bose Music app on your mobile device, add the soundbar to your Bose Music account and reconnect it to your network
