"Letting customers fall back to the older software could ease their frustrations and reduce at least some of the pressure on Sonos to rectify every issue with the new app." It's understood that Sonos wanted to push the updated app out at the same time as its Arc headphones, but that audio product only communicates with Sonos soundbars. What has transpired is a litany of bugs and app crash issues that have infuriated loyal Sonos customers who have spent hundreds, if not thousands, on kitting their homes out with audio equipment that is now not fully functional. Some people may only have one or two Sonos speakers but the appeal of buying the expensive hardware has been because you can link them all together over your home Wi-Fi network to create a house-wide web of speakers. This has meant that some people have spent large sums to kit their whole house, garage and garden out with tech that has now been rendered unusable thanks to a dodgy software update.
