9.0 Version App Keeps Freezing

The next time you have it freeze, kill it, and restart it, you might submit a system diagnostic . There would likely be data in that diagnostic that might help Sonos help you, and you'd just need to post the number here, or perhaps contact Sonos to discuss it.

Have you attempted rebooting your iOS device before restarting the app? Which version of iOS are you running?

Thank you for the reply. Yes, I did reboot my devices before restarting the app. I'm running iOS 11.4.1 on all of my devices.
I will do as you suggest the next time I have a chance. Thanks again.

I have the same problem. Have submitted a system diagnostic. Hope it helps.

Jo C - If you only submitted the diagnostic it will just set in the queue at Sonos, you have to tell Sonos you submitted it and give them the number it showed you so someone will know to pull it out and look at it. You can Twitter it in, post it here or call it in.

Oh, OK. thanks.
Have submitted another one to get the number.

Your confirmation number is: 1864273813.

That should do it, someone from the sonos forum staff should get back to you on that.

I have submitted a diagnostics, the number is 1206233040.

HI , same thing is happening for me since the upgrade to 9 , been on to sonos for over a week regarding this , but dont seem to be getting anywhere, they seem to be mentioning inteference and now saying one of my connect boxes doesnt work properly , but it plays music fine, i've trtied everything , restarting all sonos components , re installing the app , but the preblem seems to come back again ,

Just wondering here if the Sonos App is freezing because of a lack of space on the controller device?... it might be worth checking that. Another few things to try are switching off the 'WiFi Assist' feature on iOS and perhaps see what happens when you change the WiFi channel on your router and/or SonosNet in the Sonos App Advanced Settings.

Note the SonosNet WiFi channel and routers 2.4ghz channel are best if they are set at least 5 channels apart. In my case my neighbours seem to use channel 6, so I have set my own router to channel 11 and my SonosNet channel to 1.

See if these things help stop the App from freezing on screen.

done all these things time and time again , on both ipad and iphone , restarted , zones , nas drive , changed wifi channel , it always appears fixed for a short time as a simple closing of the app and re opening it resolves the issue , but the problem always comes back at some point , hopefully the more others post the issue it may get recognized and seen as a bug that was introduced in the latest release
