I’ve been a sonos dealer since 2007, when they never did updates or if they did it was to add a feature or fix a known problem. I have installed thousands of sonos products. I installed 30 zone systems. Now I hate to even recomend sonos. Why? for the last three days I’ve run around fixing new hardware on S2. Some people are experiencing a loss of zone but I have had issues where the whole system has disappeared. Today I spend almost 2 hours on hold. The tech support representavive told me there was no problem but as soon as I send a system diagnostic he fixed the issue however I still needed to add 10 zones and multiple arcs and subwoofers back on the system. Why? his answer was he’s not allowed to say but he finnally did tell me he did do something to fix the problem. I bill 1500 for 8 hr day and no I can’t bill that to a customer that has been good to me through the years however I still have to pay my workers and I can’t do it for free. Even the maid at the house said it makes you look like you don’t know what you are doing! Thank You Sonos!
