Sorry to hear that you no longer have confidence in Sonos. I’m sure you’ll find a viable alternative. However, how is Crestron integration and/or its components a Sonos problem?

So you are saying Sonos changed , didn’t tell anyone and now 2 months later no sign it’s gonna ever actually go back to normal?  Sounds like the situation every owner is in at the moment. Everyone got screwed here. 
 

At least I can use airplay SonoPhone and my fancy ikea symfonisk button panels work great still

Smart home systems like Crestron add to Sonos value proposition and help drive Sonos revenue. Beyond the new app, overhauling the APIs needs precise technical documentation well in advance and heavy involvement in beta testing. Otherwise, you end up with … this fubar situation.

Consider the untenable situation that local integrators now find themselves: they sold expensive systems and are responsible for maintaining them, yet they have zero ability to fix things or even make commitments as to when things will be fixed. It’s just brutal.

Yeah I don’t get the response of “how’s this Sonos problem”. They’ve treated their entire user base poorly and I hope people keep calling them out until they fix this mess.
