I’m not experiencing this ‘crash’, despite using my Sonos system (S2) daily. Is it possible there is a local condition causing this?

How do you determine it is crashing, as opposed to just a disconnect of your speakers from your router? What streaming company is this radio station from, and which particular station is it? Have you performed a network refresh, by unplugging all your Sonos devices from power, then rebooting your router, and waiting a couple of minutes before plugging your Sonos devices back in to power? Have you re-checked your devices for updates to the Sonos? Have you submitted a system diagnostic within 10 minutes of experiencing this problem, and called Sonos Support to discuss it?

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Hi Bruce, I have tried pretty much all of the things you mentioned already as part of trouble shooting too no avail. 

I'm only trying to listen to one of the national radio stations but it can take 2 attempts at opening then closing /stopping the app to sometimes get it to work. 

I have never experienced any issues with using the sonos app until last year when the upgrades began. There are still other features (editing a playlist) that still cannot do and I have tried contacting sonos support before with no response. 

Altogether, I'm not having a very good experience with the product anymore which is a real shame as I've always thought it was one of the best music systems on the market. 

So, what did Sonos Support say, when you submitted the diagnostic, and called in about it? I’m not sure how you got ‘no responses’, I’d think they would answer their phones when they’re working, but not 24 hours a day. Which is why they likely have a Chatbot for text based contacts. 

As I said, I’m not experiencing any issues with crashing on my system. Which makes me think there is a local issue. If I need to edit a playlist, I fire up the desktop controller on my Mac. It’s mildly frustrating that that part hasn’t been resolved in the mobile controller yet, but I can’t imagine it is for lack of trying, more for difficulty in making it work in the new codebase. And certainly, that lack doesn’t cause any crashing behavior.

My experience just doesn’t match yours. So I’m unsure what to tell you, beyond ‘contact Sonos, maybe they’ll be able to help’. 

​@Andyj3007 I can tell you that Sonos acknowledged that the user experience with the new app and firmware is that some owners are affected by some bugs while others aren’t.
 

You can Try using the desktop controller to control your radio, it uses the control protocol of the app prior to the may release.
 

There are 3rd party apps that also use this which TBH are more reliable still for playback control than the official app in my experience.
