I updated my Sonos controller on Mac (OSX 10.10.5) and updated all my sonos speakers. So my Sonos system runs on version 9.3.2 and all my speakers are running on version 9.3.
However the controller on my Mac greyed out all items under the "manage folder" in the Sonos menu.
I already have my Sonos set up since years, and never experienced this.
It worked all fine until some months ago.
Can somebody give me advice on how o tackle this issue?
