Remove the BRIDGE from your setup. If you can’t, for some reason, hang your CONNECT:AMP from your WiFi (which is highly recommended) you should try wiring that CONNECT:AMP directly to your router, at least temporarily. BRIDGEs are known to go ‘bad’ and present challenges to systems that are hard to diagnose. 

I have the same problem, and I don’t know what a BRIDGE is. In Settings → System, I see the “+ Add Boost or Bridge” option listed but I don’t think I added it ever, and I don’t see a place to remove it.

And don’t know what “hang your CONNECT:AMP from your WiFi” means. Is this a button in the Sonos S1 app? Or is this some type of a configuration I set up in my wifi router?

Thanks

If you don’t know what a BRIDGE is, you likely don’t have one. It was designed originally to be wired to your router, and then provide a signal to your Sonos to latch on to. Sonos replaced it with the BOOST, which was built better, and was faster, but that has been retired as well. Now days, most Sonos are connected via WiFi. 

You may want to peruse the second half of this FAQ. It explains the S1 controller, and how to set it up as a wired or wireless system.  

Hi,

Same problem, no bridge involved.   Most of my Connect:Amp’s are hardwired, though this has not been a problem in the past.

Thanks for any advice on how to fix this!

Regards,

Michael

Identified - We've identified a problem with Apple Music on Sonos S1 systems and are working with them on a fix. You may not be able to sign in to your Apple Music account on Sonos S1 systems until it’s resolved.

Also having same issues I’ve tried everything with Apple Support they can’t fix it - went thru hoops of resetting my phone at their suggestion it did nothing

It could be a problem with the Sonos controller, did you also call Sonos Support to discuss it?

Sure seems like, due to the quoted statement, it hasn’t yet been fixed, since there is still an outstanding service issue posted. But I haven’t called in, either.
