Aside from powering off your router and all your speakers, then powering the reboot back on, followed by the speakers (I’ve seen this sometimes given as a troubleshooting step), or else just hoping it just starts working again, you might be out of luck.

I can’t imagine you’ll get very far with Sonos or Qobuz support, as I suspect one of the first things they’ll ask you to do is install the latest updates. 

For what it’s worth - it’s working on the latest software for me. I can search for an artist, select them from Qobuz and it lists their releases.

Same here with 16.1 app. With the newer app it does show the releases as jamie72 mentioned.

Every now and then the 16.1 app shows the “Update available” on the top. I think it did so yesterday but I did not update and have blocked some addresses in case I mistakenly tap to update.

I just hope it’s a temporary issue and not something they’ve managed to change so that users would be forced into the newer firmware and app. 

Same here for 5 days. Anyone find an answer? Searching by album works, not by artist. It returns ‘No selections are available' every time.
