Hi,
I bought at the same time a SONOS 3 and a SONOS 5 speaker. Both are well registered on my SONOS account. I need to change my Sonos 5 Gen 1 which is not compatible with the new SONOS system and I want to use he 30% discount upgrade program. For a bug reason that cannot be explained by SONOS for weeks, the offer is available on my account for the SONOS 3 and not for my SONOS 5. The Sales representative does not give any help to solve the problem. I am considering contacting a lawer to sue SONOS on the principle since I bought this speaker, ii is well registered and I am entitled to benefit from this offer. I am incredibly surprised how SONOS treats its customers who want to be faithful to SONOS and buy a new product and I will protect my rights and those of the customers whatever it costs me.
