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

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

Still got this issue. Open the app - start playing playlist - close app - open app later and still showing details of track that was playing when app first opened - controls still work and will change track, stop etc. but artwork does not update. Sometimes tapping around will bring the app back to where it should be other times closing the app may make  it springinto life and sometimes even closing the app and opening it will still leave you at the first track you played.

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

I have the same issues with the S2 upgrade. I only have one Connect. It was only 2 years old and was upgradable. I have am iOS app and a PC app that takes much longer to find the system. The issue for both apps is that album art display is painfully slow, sporadic, or not any art at all. Also, user controls are no longer functional. Play, pause, volume slider are unpredictable, have several seconds lag, or don’t respond at all. I have tried resetting router, restarting Connect, reinstalling apps. This does not solve the problem.

This was a smooth, flawless system before. I believe that what I need to try is to revert back to S1. Has anybody done this? Thanks.

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. 
 

This thread should not be marked as answered

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!

I am a person who uses SONOS library - I don’t use Spotify/ etc.   I play downloaded MP3 from shows, and SONOS has to fix the lag when it comes to working with libraries and switching between speakers.   It’s drastically slow.

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.

@skilletP You’ve made two changes to your system:

• You went from S1 to S2; and
• You removed the Bridge that made your speakers use Sonosnet.

I’m wondering if your current problems aren’t more related to the removal of the Bridge. You could try cable connecting one of your speakers or buy a Boost to build a Sonosnet again.
