I never usually comment publicly, but being a long-time user and lover of Sonos I am now considering moving off to another system. System. It is useless to me, all of the functions that I used, including the sleep timer, the volume controls which are very unstable and the functionality of this new update has been horrible. Horrible. I have no idea how this was even allowed to push out to the public. Do they not have any beta testers?? Rev. Back to the old system. If it ain't broke don't fix it.
