I have 2 x sonos play 3 and neither of them will factory reset. Both were working last week, both software updated last week. But I changed wifi networks and neither would connect, so I tried to factory reset both. They both flash amber but will not go any further in the process.
I've tried many times and even left them unplugged for 24 hours but still no go! I see others have had this same issue, but I don't see any resolutions
