Controller Version
I have the PC App: Version 17.2.2 Build 90068190 and iPhone App Build: 83.01.11 - Most of my SONOS hardware is on Version 18.2 (build 94175110) with the exception of the BOOST Version 17.2.4 (build 86675110) and the Guest Playbase Version 17.2.4 (Build 86675110).
Does all of the SONOS hardware have to be at the same version level?
