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

If WiFi interference is the culprit, why wouldn’t the S2 Windows Desktop suffer the same lag issues? I have no similar issues on a Wireless Laptop or hardwired Desktop in the Windows world. When I spoke with Sonos support last week, I was told they are not experiencing this S2 issue with any customers which of course is nonsense. I am going to order the Apple IPad Air 5 and test my theory that when you have a large Sonos environment, the system bogs down and you need (at least in my case) a Tablet with a fast processor and lots of Ram.

Hi

I’m having similar issues - I’ve four systems in four locations using separate WiFi networks.  Three use S2 and one S1. Very recently, ALL apps (irrespective of S1/S2) are slow to respond to volume changes and to load search results - Amazon Music/ Hype Machine results returned seemingly instantly but Quobuz and Spotify(My go to choice) take twenty seconds or more to return results.  Using iPhone 13 iOS 16 generally but elsewhere iPads 6s or 9s using latest software.  Sonos software up to date.   Each system uses Boost for network and has 73 Mb/s BT internet.  Disconnected and reloaded S1/S2 Apps but issue remains.  Search results used to be returned almost instantly.   iMac controller still functions as it should with no delay.

No one else seems to be complaining about this, so maybe speak to either Spotify Support, or Sonos Support. It will be the Spotify servers that are returning the results, I presume.

I only use their Spotify Free service here and that gives an almost instant return. Amazon Music and Deezer, which I subscribe to, seem almost instant aswell. 

Can you perhaps give one, or two, search terms, Artist/Album etc. that you are searching for and I will happily check again, but ideally you will still need to speak to the Support Staff - I would expect to see more complaining about this issue, if it was a wide-spread issue.

It’s usually the SSDP ‘multicast’ device discovery of each and every Sonos device across a subnet by the controller device that causes the delay/responsiveness issue, so maybe try to reduce any wired/wireless network interference and maybe reserve device IP addresses in the routers DHCP reservation table. It should not take any longer than 10s (that’s just a ball-park figure) to be fully up and running with any Sonos system when opening the App from a fully closed state, at least that’s been my own personal experience in the recent past. 

Not a very helpful response.  

If I search from the Spotify app using the same iPhone or via voice pretty much instant play.   The issue re app occurs with both S2 and S1 with discreet Sonosnet systems and discreet internet accounts / routers .

reached out to Sonos help and submitted a new diagnostic from today’s house.  Travelling to the other two early next week so picking up from there and submitting further diagnostics.  I’ve had Sonos since 2010 and no issues previously.  Also yesterday used old redundancy iPhone 6 running older iOS software and still same issue.  Very strange that this happens in four distinct locations even when using controller devices which are unique to those locations 

I manage to get things up and running these days around the 10s mark (give or take). here’s a .gif (animation) I created a few seconds ago opening the iPad Sonos App from a fully closed state, that’s with 29 Sonos devices and numerous music services installed. The ‘My Sonos’ tab has no space to add any further items - so it’s all perhaps pushing a ‘worst case’ scenario. 

The App is ready to go when the volume control on the ‘now playing’ takes up its correct position (just as a reference point).

This is whilst running all on an 802.11ac WiFi mesh system.

If I open the App from a background state instead, then it’s a few seconds only.

Sorry about the quality, but there’s a 5MB upload limit here - but hopefully the repeating animation above shows you the kind of discovery speed I manage to get. I’m quite happy with that level of responsiveness. As I say it’s a lot less waiting time if the App is just brought forward from a background state.

edit: (animation now attached instead - as it was a bit of an eye-sore) … Ken

That’s okay 👍 

If I use an iPhone XR running iOS 16.2 and S2 App 14.20 build 70435282 and search, then it’s almost instant here. I’ve attached an animation to somewhat show the results being quickly returned when searching for Phil Collins, just as an example, but I mostly use Amazon Music Ultimate and Deezer Music streaming services, aswell as the Spotify (Free) service. So I don’t think it’s a glitch between the S2 App and latest iOS software.. My other thoughts are to perhaps try a different DNS server and see if that resolves the issue.

Thank you - not sure how I change the DNS server - all properties use BT routers on BT contracts as internet provider but are geographically hundreds of miles away from each other. 
 

it is effectively as if four separate households were experiencing the same issue, the only common connection being all Sonos players are identified as belonging to my account (but set up as four separate households systems) and the same issue arises whether S1 (one household) or S2 (three households) are being used, by the same (this iPhone 13 or my wife’s iphone13 which move between properties) or the iPads which remain as controllers in the specific properties.  The only controller which works as normal is the iMac (on an S1 system). 

Would someone try searching with the pan streaming service search magnifying glass instead of the browse search and see if for them the search is slow .  Thanks 

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.

Hi Ken 

Here’s the latest : Sorry - once more.  What I wrote about using browsing and then searching is generally true and returns instant results if a new search artist / album is requested which has not previously been requested using the magnifying glass - all very strange
