After the last update (late July) the dreaded 913 error has been replaced by a 1002 error when I try to connect my Mac based music library so the system is still unusable. I've removed the Boost the system was using, moved all components onto wifi, the wifi signal is strong, the firewalls are set up to allow Sonos connections, and the right file sharing permissions are in place. Does anyone have an ideas if this is still an app related issue or another problem.
(Oddly, when I switch off the firewall completely - I revert back to the 913 error when trying to add the Library)
