Anyone else experiencing severe APP LAG & slow loading/refresh with S2?

Hi, I’ve been experiencing similar issues since I upgraded to the S2 app too.

“When people OPEN their Sonos S2 app does it take 10-40 seconds to load/refresh?  Is it laggy when changing sources, volume levels? Do the graphics take time to load after the app has started?” - Yes!

I have recently bought an Amp, Move and Arc and connecting to those speakers via AirPlay and the Sonos S2 app were very unreliable (also my other Sonos speakers). As you described my S2 experience was very laggy, taking many seconds to connect to the speakers if I was lucky. As you have experienced yourself, this was immensely frustrating when spending a not small amount of money on Sonos speakers expecting them to perform professionally and very disappointing.

Since researching about this issue and coming across this community post, I’ve now connected one of my speakers directly to my router, which means my Sonos speakers are now using SonosNet Channel 6 (you can also choose channel 1 or 11) to talk to each other rather than using my Wi-Fi channels and the lag has almost disappeared (AirPlay connection reliability seems to have improved too). This may have been caused by too many devices being on my Wi-Fi router. I only carried this out earlier today, but the results so far have been very promising.

I know there has been an update to the S2 App since you posted this, so I may also be experiencing an improved service due to the App update. I hope this helps.

Same problem - takes what feels ages to load just the app. Got significantly worse over the past month or two. FIX THIS PLEASE. Incredibly annoying

My Android app loads in a couple of seconds, as does my wife’s iPad app.  There is nothing to fix.  Please see the comments already made on this thread by @Airgetlam .

This thread is over 2 months old now with a handful of posts.  Past experience suggests that when a genuine bug crops up affecting even a small proportion of users, there are dozens of posts within an hour or two.

Same problem for me.  EVERY time I open the S2 app, it takes 10-30 seconds to load.  No other apps have this issue.

update:  uninstalling and reinstalling the S2 app resolved it for me.

Similar issues here- system worked perfectly but now is laggy, and speakers constantly drop off network or disconnect then reconnect.
 

I have two separate homes, with different ISPs, different routers, different TV brands, and one with a hardwired connection. Separate Sonos  accounts. Both have the similar problems, which coincided with upgrading the app and purchasing two new ARCs. Before that, it was a totally different experience- several years with no issues at all. I’ve worked with tech support, reinstalled apps, reinstalled the speakers, but the end result is still a buggy system. 
 

It’s VERY frustrating for those of us who know something about networking to have people on these forums keep blaming the network. I can tell you, it is not my network(s). And even if it was, how can it be that every other product or gadget I have ever purchased did not have these issues (including Sonos prior gen), but Sonos does.... this is a relatively mature company and technology.

The fact that SO MANY people are complaining about the same issues makes it clear that this is a problem… just because your system works doesn’t not prove that the software is fine. There are several other forums with similar complaints. These are speakers, and the core functionality of playing audio content should not be so fickle. 

It should not be this complicated or frustrating for people with otherwise functional home networks and hardware to use a Sonos product. Period. Its even worse to degrade the experience after users invest considerable dollars in a closed ecosystem that used to work consistently. 
 

Same problem. App takes ages to load. 
 

I am using a Velop mesh network and can video conference reliably throughout my home. But Sonos app struggles as do some speakers. Pressing play/pause can take 10 seconds to have an effect. Ditto volume controls. Not far off wanting to switch to something else. 

S2 app is a joke.

I like the quality of the Sonos hardware, I like the support people I’ve been in contact with.

But the S2 app is an embarrassment. Slow, unstable, with bad communication to streaming services.

Same. Painfully slow load and lag with S2 on iOS. Super frustrating to open the app bad have to wait 30+ seconds at times for it to even load. HALP

Maybe get it to do a slow load and submit a diagnostic? If you post the number here or call Sonos with it they may be able to tell more.

Even the PC app takes an age to sort itself out and load. Slow updating on Android, used to be a really quick to load but obviously doing too much at startup.
