we have just about every Sonos product they make and this latest update prevented us from using any of the speakers until we were able to reboot our router, unplug each device (about 25 of them), and keep launching the update. It made me realize how much we have invested in Sonos and how one issue like this could cause us to potentially flush thousands of dollars down the drain. We will be looking for alternatives in the future rather than buying more Sonos products. This is absolutely unacceptable for speakers with such a high price point!
