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

Hi …thanks - I don’t get that - yours works logistically and the options become less and quicker as you hone down with more letters. Mine stutters and restarts the search. 
 How do I do the Gif screen shot ? 

I really don’t doubt what you’re seeing, but anyhow, I simply record a screen-capture video and then use an App called ImgPlay to convert it to an animated.gif (other Apps are available) - The only issue is the upload limit here in the community is 5mb - so the quality is affected greatly with such a small file size limit, but usually when compressed to 10fps enough detail can be shown to demonstrate the issue in the finished uploaded file.

However, moving on, it would be more interesting to see if you get the same issue with an Android mobile controller and also, you could perhaps consider shifting the local system (whichever one you’re nearby now) over to perhaps a mobile wireless connection instead, particularly if you have a decent 4G/5G LTE connection available to the Home environment and see if eliminating the BT connection improves the matter. It’s also still worth trying a different DNS in the router configuration pages, thats if BT routers allow that?

Hi thanks once again.

I wasn’t suggesting that you doubted what I see; the purpose of uploading similar video was to demonstrate to the community/ Sonos what the issue is.  There are a number having similar issues on various threads but probably small relative to all users.  Don’t think the solution has ever been bottomed.

My son came over yesterday and the issue is the same with his recent Android. 
I’ve no means of moving the router to 4/5G unfortunately (there are back up devices available on some ISP packages but I don’t have one here).

Hi Ken - thanks for your many suggestions.  I’ll try hotspot as last resort since everything set as wired through boost to router.  I’m going to another home with Sonos /BT in two days so I’ll see if have same issue there - that will rule out issues with individual networks etc 

Finally I’ve found the solution to the laggy controller in my case.  Out of my four households, I found two (S2) were functioning with no search/ app control lag.

The other two households (S1 and S2) were both experiencing the same issue of severe controller lag, sometimes not even returning search results.

I’ve submitted diagnostics from the two affected households and it was discovered that each household had “phantom” players (not visible in the app but picked up by the diagnostic) belonging to the other laggy household.  There was therefore some confusion over the network of speakers. I had upgraded some speakers and given a couple away but moved a Play 1 between houses.  Seems the factory reset may not have been effective and caused a bridge between the two households.

Finally resolved in one of the households (not yet visited the other) by totally factory resetting everything.

(That in itself was a nightmare since in the time since I originally set the system up I’d changed the router from BTHub6 to BT Superhub2, just by changing the wired connection from the Boost to the hub with no resetting required.  It wasn't apparent then since effectively I just “plugged and played” a ready configured system, that starting from scratch with Superhub2 would be so problematic.  Unable to get any speakers to be found other than eventually the Boost, but even hardwiring other players to that wouldn't connect.  Numerous repeated factory resets to no avail. Sonos help on the phone for longtime with suggestions but still no success.  Apparently there was an issue with original Superhub2 software in 2021 but this was fixed.  Mine is running latest version.  Fortunately I had the predecessor BTHub6 and setting up Boost and Sonosnet using that was relatively straightforward (with few connection problems which needed hardwiring / factory resetting (again) before finally up and running.  Then switched Boost and connected system to Superhub2 ethernet and it continues to work fine.

Hmmm, my 2 Canadian Cents (so not much value) … on my Desktop or Laptop (Windows) loads fairly quickly and is snappy when I want to make changes. When I use my Lenovo Tablet (M10 Plus) a year old, Oh Sweet Moses, … it sometimes won’t add zones. Searching Google, I deleted all active Widgets on my tablet Home Screen and Icons I really don’t need that bad but were nice to have and S2 was better. The 2 Year old Samsung Tablet I have confirmed I was on the right track as it was faster than my newer Lenovo Tablet. Bottom line for me is that while SONOS wants us to move to newer devices that support future processing the current Tablets don’t have the horsepower to do this. 

Hi - thank you for your observation.  My issue was - eventually diagnosed by Sonos - is that somehow two of my four homes had infected each other so both was seeing not only its own speakers but those in the other home too and clearly they were many miles away on a different network.   Everything was left unresolved when searching.,,,

Had factory reset everything to solve.

S1/S2 Agnostic since issue affected both equally 

That’s a bizarre assumption that the CS rep made. I don’t even know how the Sonos controller could “see” across different networks. That particular case has been an issue for lots of people who run different networks in their own home. To be able to see across distances where the networks aren’t even in the same place seems….well, ludicrous. 

But I’m glad that a factory reset solved the issue….but I really have to think it was something other than what they told you. Just doesn’t add up, to me. 

Whilst it may seem incredulous rather than ludicrous, it is factually correct!  When I submitted diagnostics for both errant homes, he was reeling off speakers by name which were part of the other and vice versa.  I have moved speakers around my various locations and possibly added one without a factory reset - that may mean it brought with it the baggage of other speakers from the other location.  I don’t know how but I do know what the Sonos guy saw because he was able to read out the speakers by name, not all of which were in that location.  If safe sex is always practised, there’s no risk of STI transmission.  If i took a risk (not intentionally) of not taking protection by factory resetting, then I see it as perfectly possible for the cross contamination to have happened.  But I don’t know what happened for sure, I’m only speculating why.  But the effect of whatever happened was very real and correctly diagnosed by the Sonos guy.
