Why is Sonos App so bad and why won't Sonos fix the problems?

If other music players can better tolerate your network configuration, I suggest that you stay with them. If you can describe your network in detail, we can suggest some more functional network configurations.

Are you from Sonos? If you are, my simple answer to your suggestion is: no. You need to fix the App. Why do you refuse to fix the App? There is no reason why it keeps losing connection with the network, I am sorry. I use Community Fibre here in London, with a very simple standard set-up. You need to support it. Your refusal to admit or correct the issues is even more frustrating than the issues themselves. 

Please escalate internally.

You are on a User to User forum, with a very light presence from Sonos Staff and all of them here officially have that clearly shown on the or profile name.

The Sonos App doesn’t carry your music, the players do, while the App just sends them commands.

Oh, and it is almost always your network. It is very rarely the network you connect to so London Fiber is more than likely innocent.

Sonos and its (remote) controller App work fine for the Wife and I and everything is really stable on our LAN subnet. So my thoughts are it’s likely your controller device and/or your network.

If the App loses connection to your Sonos devices it’s probably an SSDP (part of the UPnP protocol) multicast ‘device discovery issue. Maybe explore that possibility with your network provider and check your local controller device for things that may interrupt the device discovery packets, such as VPN clients, security software, mobile data interruptions and background tasks. 

The Sonos software is the least-likely cause of the issue here, otherwise it would not work for my Home setup, or other family members and our friends …and they do not have any connection-loss issues either. 

You need to look local to likely find the answer to your Sonos issue.

We are mostly volunteers. SONOS employees are clearly labeled.

At one point I had major issues with my SONOS system. The cause turned out to be a neighbor’s cordless phone system, known to trash the wireless environment. After adjusting a player’s physical location in order to avoid the phone base station, along with proper configuration of my network, my issues were resolved. That was in 2005. If I had system disfunction such as you describe, I would not be here.

I’m not familiar with Community Fiber. Maybe another user can help with some configuration suggestions.

We all have our idea of how a “proper” App should interact with the user. Millions of people think that Apple has the best user interface. I’m not one of those millions. If Apple “fixed” things in order to satisfy me, millions would be angry. I do have some Apple experience because I must use an iPad for work functions.

Lots of toys being tossed from the pram, not much in calls for help.  I'll pass.

In your original post you claim to have “raised this issue multiple times” yet your user profile only shows activity in this thread.

You claim that “the Sonos App is badly coded”. How did you access the code itself, to reach this opinion? 

If the app is so bad that “IT DOES NOT WORK”, why aren’t there thousands of users complaining? 

Sure, the app could be improved. But if you mean “I’m having problems with my system” and the symptom is poor connection with app and speakers, your network is the likely place to look first, as has been suggested in other replies above.

Why not try that route first? It has been the solution to unreliable connections for many other users - including me. I was sceptical that my network was at fault, but a flush of the system (power down, then a phased restart of devices) and then allocating ip addresses to my speakers has fixed things for me. 

Did you find any way to use it smoothly? or it’s still crashing?

Who are you asking? My system has been stable and reliable for years. 

The app is total junk!
