I can beat that!!
Over 4 hours on Live Chat and then the phone today trying to find out why the system fails every time I try to do an update.
Attempted on both the Android App and the Windows Controller.
I was going round in circles with support, being told to try the same things over and over again. Surprisingly with the same result each time. Failure to update.
Must have rebooted the router, deleted and reloaded the Apps, powered off and on the Sonos speakers around 10 times, all with no luck.
2nd level support also involved and after all those hours wasted, they then told me that the update was not yet fully available on their server and that it should be complete by tomorrow. So please try again tomorrow and here is a ticket number if you need to contact us should it fail.
Sounds like nonsense to me, but given the fiasco over the new App roll out last year, nothing would surprise me. Surely if they knew the update was not fully available, why not advise their support staff and save everybody wasting their time.
