Sonos App super slow - Because I have all old devices, or is it likely Network?

Here’s my setup

Unifi UDM-Pro, 1 x U6 LR, 1 x U6 Mesh, 1 x AC Pro. Dedicated Sonos SSID. Flat VLAN (images of my SSID configuration below).

mDNS and IGMP Snooping enabled on the LAN interface.

All the Unifi devices are running the latest early access firmware available.

2.4 GHz at 20 MHz (never put any 2.4 GHz to 40 MHz even if it sounds faster). Transmit power 12 dbm. Minimum RSSI 72 dBm with Interference Blocker enabled.

5 GHz at 80 MHz, Transmit power 18 dbm, Minimum RSSI 72 dBm with Interference Blocker enabled.

So, if it’s not capable of maintaining a signal of at leat 72 dBm, it’s being kicked out. That guarantees me a good ground base for a solid connection. If it can’t connect, I need to take proper action.

11 Speakers split in a few: Move, Play:1, Play:3, One, Sub, Roam

Recently, I started having some issues on 2.4 GHz so I switched to 5 GHz (I don’t have a home theater setup).

That fixed my problem (major 2.4 GHz interference in my building).

Also, for those of you using Unifi gear and a UDM-Pro (or the same router family), remember that it does not support STP, only RSTP. So if you have Sonos gear connected to the UDM using Ethernet without disabling the WiFi interface on that gear? You will have loops and network problems.

Also, lately I got fed up with all the publicity online so I installed Pi-hole at home as a Network-wide Ad Blocking. I love it but it also blocks msmetrics.ws.sonos.com out of the box. That played havoc with the mobile app. Slow app, slow control, speakers starting song seconds after I pressed “play”, stopping songs seconds after I press “pause”. Bottom line? If some of you are using Internet filtering software, have a second look at it. Once I whitelisted everything in regards to Sonos, everything started responding quickly again. Sonos needs fast and responsible DNS to work good. I learned the hard way.

All my mobile apps are now running smooth.

Hope it helps, espacially those with Unifi gear.

So here's my guess on this issue.

My suspicion is that Sonos are doing more monitoring of control actions on devices from actuated from the new app. Worst case would be a volume up/down action making a blocking remote call to report in at HQ. *If* they are doing something like that - with millions app instances running they'd need a lot of servers to handle the calls.

Could be app debug logging - something like sentry.

Pure speculation on my part.

At an observational level, when I move a volume slider what I see is the slider move back to the old state, pause (a few seconds) and then jump back to the new state and the volume the actually change.

Having the same issues. Using UniFi from Ubiquity and a few different older Sonos speakers. Not Sonos S1 but still a bit older. Hoping a solution shows up soon. Getting ready to leave Sonos after like soon 15 years of use but for what. Very few alternatives around…

FWIW I've now downgraded 4 of my 5 Sonos devices to S1 (leaving one so that I can keep an eye on the new app). Far more responsive, stable and usable. Just have to ignore the nag message to upgrade to S2.

That's 3x Play 1 and 1x Connect down grades to S1 and a single Play 1 left as bleeding-edge S2.

I don't class moving from S2 to S1 as a downgrade.

Hi all

I noticed a significant boost in app performance after attempting to deactivate Sonos Radio. 
 

All I managed to do was deprioritize it by setting Deezer as my preferred service. 
 

hope it helps

Save yourself some time and pain and just go download SonoPhone and pay the $4. My whole system is back being responsive like the old days. Volume is real time and switching songs is a breeze. I was about ready to sell my entire 7 speakers setup!  Sonos should be thanking this developer. 

Old and new here. 
sonoPhone - instant response 

Sonos app - 3-10 seconds lag. For volume changes/turning it off even. Unusable. 
 

1gig internet fibre to the kerb, one router. Bt. 
 

the app sucks 

FINALLY SOLVED THE ISSUE WITH SLOW RESPONS USING THE SONOS APP!

I've also spend huge amounts of time figuring out why my system doesn’t respond or was very very ultra slow responding to volume changes or ‘next song’ in the Sonos app. After reading your comment I installed the app Clic.

Immediately everything works smoothly as it is supposed to work.

My network never had any issues, but I got confused by several people in fora claiming it had to have something to do with double IP addresses or network settings and rebooting the router and so on.
 

I didn’t change any settings in my network, I only switched to Clic and finally the system works as it should. Next I also installed the Sonophone app. And while using this app (that also worked fine) I suddenly noticed something else! In the Sonophone app you can see the list of songs in the queue of the speakers. It took the Sonophone app a while to list them. It appears there were over 2.000 songs in the list. I replaced the songs in the queue and suddenly even the Sonos app had reasonable respons times!!

Now my theory is that the Sonos app takes ages to load the playlist (songs in queue) first before it can respond to the changes in volume or go to the next song in the sonos app. But once the songs in the queue are gone, the speakers respond quickly, even to the Sonos app! I wonder if this would solve issues for others struggling with the slow respons times of the Sonos app. 

How many songs are in the queue of the sonos speakers?
