I received the email that Sonos was not going to support my speakers, so follow the link to see what 30% off on new speakers would be. Still way to high for the same sound I can get with my original speakers. Never completed the swap, but just got an update on my Sonos app that 4 of the speakers I would looking at to replace will be deactivated and not work any more in my home. I called customer support to have them turn off the deactivation and they said, “sorry we can’t - we don’t have a delete key”. Are you kidding? The CEO said they will support the older models and because I looked at a possible upgrade, they will not let me back out? Something is way wrong on this one.
