Rather than starting with a rant why not tell us what Sonos gear you have, what device you are using and is it up to date. As far as your network is concerned we need to know about it as well. Such as type..,is it a router and modem or Mesh? What brand of network gear or is it provided by your ISP? Have you checked your network gear for updates? Help us to help you. 

I have a regular modem/router with a rock solid gigabit connection. I have never had a momentary blip in perfect fiber service in 5 years of living here. 
 

I am sitting one foot from my router. I am using the latest iPhone. My house is 1,500 square feet with perfect WiFi reception everywhere. 
 

I have 3 Ones, a living room with paired stereo Ones and a Sub, and a media room with an Arc, paired Ones as surround, and a sub. 

They randomly pop in and out of existence in the app including “about my system”. The app randomly just doesn’t load images or sections of the app altogether, just the loading animations and gray background. I’m getting random errors like “cannot load” recent playlists. When devices are recognized they randomly play music or respond to my volume controls or not  

So I’m having many overlapping issues all clearly traceable to the new app. I could get a degree in computer science and join Sonos as a full time employee. Or they could just fix the app which worked perfectly before whereas zero variables on my end have changed  

Thanks for the reply.

If all systems are “go” then I suggest you run a diagnostic on the Sonos App within ten minutes of the next occurrence and post the reference ID in this thread. Then call Sonos Tech support on Monday to discuss the results. Of course running the diagnostics assumes you are able to load the app on your device.
