Well, I thought we were over the worst of it.  Christmas coming and I have friends round.  Sonos playing away happily- fourth track plays and bam - nothing.  No products found.  Thanks Sonos.  

This is so far beyond a joke, it’s shameful.

Edit,  No items showing on ipad, android or web.  I wondered if my TV would still play sound through the ARC.  I went and turned the tv on and yes the ARC plays.  At this same point the system reappeared in all places…..kids had been watching TV, I don’t know if them turning the TV off coincided with the music outside stopping.
