When are you going to fix the Sonos App and response time?

I don’t have significant delays/lag in my system. 

Most often, delays are caused by network issues, between your controller and router, or the router and the speakers. I’d certainly check the wifi interference FAQ, as well as performing a Sonos network refresh, by unplugging your Sonos devices from power (or powering them off, if battery connected), and rebooting your router. Once the router has recovered, power back on your Sonos devices. This will give them both a fresh IP address, as well as a refresh of the Sonos OS. Finally, check your system for updates, in case there are any that need to be applied. 

For what it’s worth, replacing a router doesn’t fix many of the issues that are covered in the above process, as each device which is left powered in when changing the router should normally hold on to its previous IP address. 

There was never an issue before the infamous update. Post update, everything ran terribly. I spent 4 hours on the phone with Sonos technical support. They guy was good, we tried everything. The only thing that changed was the update. So, I cannot rationalize the idea that my set up / environment is the issue. From the sleuthing I was able to do, I found that the update was done for the newest line of speakers they were rolling out. That update was rushed out the without necessary testing. Thus all the updates since. Management was in a rush to get the new speakers to market and failed to listen to their own employees. The last sentence is conjecture, but logical. 

Ah, I see. You’re more interested in conjecture, and assigning the blame elsewhere, so you can post a complaint.

Why did you post in this community? Had I known you weren’t interested in assistance, I’d have not bothered. 

The May 2024 update has made Sonos systems more susceptible to disturbances by relying more on outside connections - I believe even volume commands are routed via the internet now. This means disturbances that were already present in your home environment but did not present problems, could present problems now. Especially older Sonos devices seem to react badly to this change.

This would mean the problems weren’t caused by the update but became apparent after the update. This subtle difference that makes it hard for Sonos to mend problems.

Complaint for sure. Justified? Definitely. Sonos provides the same “help” answers you did. Instead of admitting their mistake in shifting to cloud based control vs. Local control, they offer platitudes and non-help answers like reset your router. Like a moron, I’m waiting around to see if this Sonos environment improves with future updates. I’m not holding out much hope tho. It’s only because I don’t want to sink thousands in new equipment to replace what I have invested already. The only reason I can think of to move to cloud based control is so that they can switch to a fee based subscription service in the near future. When that happens, it all goes in the garbage anyway.  My apologies.

That sounds about right. However the question remains What possible justification for routing my “volume up” or “next song” through their servers could this possibly be required? 
 

somebody sitting around a boardroom table somewhere said “hey I’ve got an idea. For absolutely no reason, let’s move our customers commands from local control to cloud based control. Let’s route their commands through our servers. Surely you can all agree that that’s a fantastic idea, right?” 

Sonos has repeatedly denied, on this forum and to the general press, that they are moving to a fee based subscription model.  Matter of fact, the website starting that rumor was so off-base, they had to put a disclaimer in the very article that proposed it.  

dude. https://arstechnica.com/gadgets/2025/03/sonos-reportedly-cancels-its-plans-for-an-apple-tv-streaming-box-rival/
 

this is why. That f*****, exactly as I “conjectured” is true. 
it cost them hundreds of millions in market share and people lost their jobs. I’m hoping it was the idiots who greenlit this lost their jobs because they didn’t listen to their customers or their employees.

There is nothing in that article (or any other about the streaming box) that stated or implied Sonos was moving towards a subscription model.  Might they have provided subscriptions for streaming services?  Sure.  So do Fire TV,  Android TV, Apple TV, Roku, etc.  But not one of those devices are unusable if you do not buy a subscription, subscriptions are entirely optional.  Which belies the definition of Sonos “switching to a fee based subscription service”. 

And . . . . .  they killed the damn thing.  So even if it did mean Sonos was moving to a subscription based service (it didn’t), them killing it basically kills the rumor.
