My Question or Issue

Recent update broke Spotify connect to Sonos over VLAN. I have an iPad with an old version and it works perfectly.

I have a main subnet and an IoT/media subnet. MDNS is setup to repeat. Connectivity to the sonos speaker works fine via the sonos app.

Switching to the IoT subnet shows the sonos speakers.

The iPad version works in either subnet.

Yep. MacOS has been fine, for me. MDNS is not involved in my network, though.

It's now 2 weeks for me, and using Spotify via Sonos app works, but is less than ideal. I assumed today's release would address the problem. Nope.

I have the same problem now with my mobile Spotify app... Sonos can find everything, Spotify not. But Spotify from Sonos app works.

I have this same problem - any known solution?
