This has been mentioned to Sonos in the past, no clue where it sits on the bugs to be fixed list.

If you set the App to stay active in the background does the  not-found still appear?

Hi,

Are you saying set the Sonos app to stay active?  I’m not aware of that setting.  If the phone stays on (longer screen time-out) I get no messages but that’s really not what I want to do.

Thanks

Background activity is in the Android app settings, not sure about Apple.

I have an Android.  I’ll check it out.

Thanks

My guess is that the app is ‘scanning’ for the connected speakers every time you open it, and showing that message until it ‘finds’ the speakers. Since most of us don’t seem to see this, it suggests a local slowness in your network. 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.

From here it really seems to be a timing issue as keeping the app awake in the background eliminates it. 

Here a couple seconds more scanning time would avoid it.

Having a "Connecting to your Sonos" appear instead would be more user friendly and save the not-found message for when the scan gives up.

Not saying it might not be a network slowness issue, just that there are more user friendly ways to deal with it on this screen.

I’ve found that I must reboot my gateway once a month or things start getting weird. I’ll have slower than usual startup, updates that take forever, complaints that my WiFi isn’t working, players not found,  and tracks that might not play for more than a few seconds.
