This is a Sonos update issue.
Once again, Sonos has applied an update without first testing it properly to ensure there are no problems.
The update before Christmas resulted in my having to purchase a new tablet with upgraded operating system.
The last update resulted in the album art from my NAS disappearing.
And today's has resulted in my four Sonos 1 units becoming useless.
And then Sonos have the cheek to blame Virgin!!!
Please delete the latest update and sort out the issue you have with Virgin before applying it again. Your treatment of customers is disgraceful

Happy to hear it's working again. We did get confirmation this morning from VirginMedia that the routing issue has been resolved.
Let's keep an eye on it and let us know how it goes in a couple days. If the system has any issues again, please submit a diagnostic right away.
