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

Ever since we took the plunge for S2 (including upgrading/purchasing 6 new Sonos unit for S2 compatibility) it’s been a real mess (system stability and WiFi issues)!

The iOS version of the S2 app is very slow to load, lags almost always, and has a terrible screen refresh rate compared to ANY iOS app we have in the household. Now 20-40 seconds might not seem like long for an iPhone/Pad app to load/refresh, but if you’re trying to get some quick control over the volume or switching songs this is a STUPID amount of time!

S1 was almost instant across all platforms and apps. While I realize Apple can take some blame for issues with iOS apps, why is S2 slow on PC and Amazon Fire (Android) devices as well?

I’m guessing I’m not the only one, but Sonos sure seem slow to address this no matter how many times I’ve reported it to support.

Anyone else think this degrades the Sonos experience beyond the obvious annoyances (especially compared to the hundred or so other apps we use with NO lagging)?

I’ve got no lag, on my 18 speakers and 5 controllers, using S2. Which makes me think there’s a local issue in your system.

I’d suggest three things to you. First, review the wifi interference FAQ. There’s some potential that your system is troubled, perhaps by outside influences. Worth reading through and applying what solutions are presented.

Second, try a network refresh. Unplug all your Sonos devices from power. While they are unplugged, reboot your router. When the router comes back up, go ahead and plug back in your Sonos devices.

Third, if neither of those work, system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it, or post the diagnostic number here for a Community Moderator to pick up.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, there are more options available beyond just the diagnostic analysis.

Thank you once more. I’ll try with an Android controller over the holiday period when we have visitors. Unfortunately we are an Apple eco system household(s). Given I have no issues when using my MAC controller (Sierra) seems to point to an iOS issue (used in various forms by other controllers).

I hear what people say about BT (and other ISP) routers being a potential issue but I’ve discounted these for the time being since the router models are common in every household and functioned perfectly until a month or so ago.

(The other strange aspect is that the search results return those for Apple Music and Hype Machine almost instantaneously but not for my principle subscription service of Spotify.

Ken’s earlier post about checking ‘Private WiFi Address’ is probably a good one.

As stated, I’ve not had this experience, and I’m also 90% Apple, with two iPads, an iPhone, and two Macs in use. For S2.

Further piece of information - each household uses voice enabled speakers on Sonosnet Boost setup. The same routers are also connected to Philips Hue via Hue Bridges wired to the routers. Voice commands for music and lighting work perfectly with no real delay. The lag appears to be confined to when using iOS devices.

..,and the issue seems the same whether using S1 (one household with one legacy Play 5) or S2 (three other households).

I’ve also a Hue system, and run a wired network. Voice commands and iOS devices are working without any delay. Have you tried to submit a system diagnostic within 10 minutes of experiencing this problem on at least one of these systems, and called Sonos Support to discuss it? It’s entirely possible that they might see something in the details of the diagnostic that those of us who don’t work for Sonos can’t see.

Just eliminate potential cause being Private Wifi address - toggled on / off /on - no difference to performance in either setting

Now you just need to call Sonos support, and give them that diagnostic number.

Now in a different property using S2 this time. Same issue even though totally different Sonos household and different router. Searching within S2 app just hangs bit can play immediately if search from within Spotify app. Matters not if I use my iPhone which has travelled from one home to this or an in unit iPad controller which is only used here

Since the controller is talking to the app running on the speakers, unless there’s an issue with the controller device talking to the router, it shouldn’t make any difference which controller you’re using.

I’d suspect a duplicate IP address issue at first blush, although DNS issues can’t be ruled out, there are a lot of things involved with network events such as a search. This is why a diagnostic submitted within 10 minutes, followed by a call to Sonos, who has the ability to read them, is helpful. We peons on this forum don’t have access to that hard data.
