Hi,
About a year ago I posted this:
At the time it was stated that Sonos knew there was a problem with Music Libraries which were hosted on a drive connected by USB to a router. But there was ‘no timeframe’ for a fix.
It looks like this is still an issue. I’ve just had to set up a new router and when I’ve pointed the Sonos towards the location of the new library it’s crashed the Sonos.
Is this being worked on?
