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

I’m the same.
 

Ever since switching to S2 I’ve had severe lag problems.  Never had them before with S1.  I hadn’t complained on the forums as I thought surely they will update the app soon. But many months later and nothing has changed.
For me, the app refresh lag can be up to a minute and it’s impossible to control anything during this period. Sometimes this even causes my speakers sound to lag and they come on 20-30 seconds after other parts of the network start. Generally I must say that the upgrade to S2 hasn’t been a good experience.

It was also quite annoying to be forced to upgrade because you buy more products! I bought a Roam and it only works on S2 forcing my whole system to S2. 

Sonos, please consider the customer experience when releasing products. Many of us are long time supporters and great advocates for the product amongst our circles. And please update the app!

My Sonos system became unreliable lately. Speakers drop, lose their pairing. And S2 is awful. Slow to load, sometimes not showing devices. Every time the screen saver starts on my AppleTV I know that I’m in for an annoying few minutes of waiting for the app to load, waiting for devices to finally appear . . . It’s painful. And yes, I’ve rebooted things, reset speakers, etc. These issues are new. Go back to May and everything was great.
 

It’s definitely the app. I just paired my Arc with a Play5. The lag was incredible. 
 

Also, I don’t want to hear from the troll who says this isn’t an issue because the thread isn’t packed with people complaining. This is a real issue.

Pretty sure John B didn’t write the app, as he isn’t a Sonos employee.

@Anthony George .  This thread is five months old and has unearthed a handful of users experiencing this issue.  There are millions of users out there using the app.  The app is just a remote control and its speed is 99% down to network communications.

So if you choose to dump Sonos rather than sort out what is actually going wrong, that is your loss.

I am having the same issue. iOS App takes anywhere from 20-60 seconds to load/refresh. Even after I have opened the app and playing music, if I go back into the app to change the volume or the song, I experience this lag. Terrible user experience!!

I’m just throwing my experiences into the ring for whatever value they are to others...

Background: Up until two weeks ago, my Sonos system consisted of four Play:1 speakers, a Connect (gen 2), and a Bridge. I then purchased a Sonos Roam and had to upgrade my system to S2 (and also lost the use of the Bridge).

App on iPhone (running iOS 14.5): While I don’t think the lag I have experienced is as much as some other people, there is definitely longer lag than with the S1 Controller. For me, the largest lag is with opening the app and it can take 20-30 seconds to populate anything. Typically, when I select a song or radio station, etc. there is also more lag than there had been with my S1 Controller -- maybe 10-15 seconds. Occasionally, it just spins for a bit and nothing actually plays and I have to select the music again. And as others have mentioned, the artwork is often not showing up, or well behind of the music. This hasn’t affected what is playing or the ability to control what is playing. Finally, another issue I have had is with the app is, at times, when I have been scrolling -- especially through my music library -- it will reset me back to the top (much like a webpage when you hit refresh will often put you back at the top of the page). This doesn’t always happen, but it happens enough to be annoying. I did not have that problem with the S1 Controller either. 

App on MacBook Air (running macOS Big Sur 11.2.2): For me, this app has also been glitchy. It is a little slower than the S1 was (as best as I can tell), though not as slow as the phone app, which is why I have begun using it more. But it does constantly have a glitchy appearance. Basically, every few seconds it looks like the whole thing “resets”. The names of all my speakers stay put, but whatever is listed as playing disappears and then reappears. So, for about 5 seconds it looks normal, then for one second words disappear from the screen, then reappear. This is even more noticeable with album artwork because it does the same thing on this app. It will look normal for a few seconds and then vanish (replaced with the default icon) for a split second and then come back. It doesn’t seem to have any impact on the functionality of anything, but it sure is annoying to look at. 

Overall, I miss how well the S1 Controller worked in comparison to my two weeks using S2, but I am hopeful it will become more refined over time.

I have tried the “solutions” offered in the answer and agree with you @Trenty. This should not be marked as answered.

I have 10 unit system and there is no lag when it comes to playing music, but the S2 system is pure *nonsense*.  Very slow to open, and each time I try to add a song it is spinning wheel time for 5-20 seconds before it tells me it is either added to playlist or not available. 

It was working perfectly until i upgraded to the S2 system and ever since it has just not been the same. I have even tried deleting the whole system and setting it up as new, but to no avail. 

I’ll contact the support team next (my own damn fault for not doing it earlier). 

Good luck everyone!

Seeing similar stuff. Changing from one album to another is also slow. The music might start playing but refreshing of the visuals is slow. 
 

The original app was snappy - even on an old iPhone 6S. This one is laggy. No changes to my network and other stuff. Just update from S1 to S2. 
 

Ironically the S2 demands fast response from sources. Like my NAS that holds our music might take 2-3 seconds to wake up and serve a song to the Sonos system. That’s too long time and the S2 app will report an error and that the song is not available. Try same song 3 s later and it works fine. 
 

That is different than my slowness issue, I’d sure send in a diagnostic and ask Sonos to look at it.

Except that mine still only takes 2 seconds to load, and this thread still has only a few posts after nearly three months.

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.

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.
