Android App issues after recent app & player updates (Unifi)

Seeing this since the last update too…

I'm not using UniFi and have a fairly standard network set up which has not changed. I have never seen this issue until now.

I’m not experiencing this on iOS…using a non unify system. I would probably submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. This way, there’s a data point that CS can provide to the engineers so they can trace this issue. Don’t post the resulting diagnostic number here, Sonos’ lawyers get sensitive about GDPR, I suspect.

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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

I’m also seeing the same issue on my network with pfsense and vlans, I have the proper ssdp/mdns setup and the app works fine until it’s been sitting inactive for a while, kill and re-launch solves it.

Thanks. Definitely sounds like a regression introduced into the Android app but not into the iOS app. Independent of network vendor being used.

Not seeing the issue with my pfSense and AP setup which doesn't use VLANs, this narrows the issue a bit.

Have the same issue, was working ok, now not - Sonos on IoT network, Android Sonos App.

Also using VLAN, worked in V81 of android app, stopped working as a result of updating to v82. Full details here: https://www.reddit.com/r/sonos/s/PCieJzmXBg

I’m having the same issue on Sonos Android app version 82.00.45, whereas the issue is not present on the iOS Sonos app. My network is the same setup with Unifi hardware, the Android phone on a trusted VLAN and Sonos speakers on IoT VLAN. I have mDNS enabled and firewall rules configured to allow communication between the two VLANs on the necessary ports, and have a music library set up on a computer on the trusted VLAN that is working properly to stream music to the Sonos speakers. In addition to the iOS app not experiencing this issue, downgrading to v81 of the Android app resolved the issue on the Android device.

Update: Tried today and problem seems to have gone. App is now stable when opening after putting to the background - v 82.01.9

Anyone else seeing the same?

There is a new firmware update that was released this week: 82.02.12 on my iPhone and 18.2 build 94.1-75110 for the speakers

Go into settings and check.

I just updated my Sonos One stereo pair to firmware 94.1-75110 and have android app version 82.01.9 but the issue is still happening.

I tried rebooting the speakers after the update but am still having to kill and relaunch the app when it's been sitting in the background.

I too have this issue. It’s restricted to the latest android app (82.00.45) , apple works without issue and if I downgrade to the older Android app the problem goes away and everything works wonderfully. I’ve had a ticket ongoing with support for weeks. Initiall I was told that the sonos devices and controller all need to be on the same Vlan to work but once I manage to get the issue escalated I got some assistance. However, support consulted with the engineers who came back and said that the latest version of the app must have exposed some issue in my network. Tiis is the behaviour I consitently get with the controller on my standard vlan (wifi) and the speakers on my IOT vlan (wifi):

Open Latest version of app:

• Latest version of Apple app: Everything functions as it should
• Latest version of Android app: Everything functions as it should
• Older version of Android app: Everything functions as it should
• System browser and mDNS Discovery apps on Android can see all _sonos._tcp.local services 

Switch off wifi (while the sonos app is open):

• Latest version of Apple app: Cannot see Sonos system (as expected)
• Latest version of Android app: Cannot see Sonos system (as expected)
• Older version of Android app: Cannot see Sonos system (as expected)
• System browser and mDNS Discovery apps on Android cannot find any _sonos._tcp.local or any other services (as expected)

Switch wifi back on (while the sonos app is open):

• Latest version of Apple app: Sonos system can be seen again (as expected)
• Latest version of Android app: System reports "No products found on TNF" (Not as expected). Only closing the app and restarting it will re-establish a connection with the sonos speakers. Sometime a force stop is required.
• Older version of Android app: Sonos system can be seen again (as expected)
• System browser and mDNS Discovery apps on Android can see all _sonos._tcp.local services 

Support tell me, "Android app's cache or discovery service getting 'stuck'. Since the app relies on mDNS (multicast) to find the speakers, it sounds like the app is losing the thread and needs a hard reset to start listening again". As the _sonos._tcp.local services remain clearly visible in Android through the System browser and mDNS Discovery apps, and the old Sonos App manages to find the speakers again, it all points to an issue in the latest version of the Sonos app. This is further supported by the fact that simply closing the app and reopening will more often than not permit it to see the speakers again. However, If I connect my android phone to the IOT wifi (IOT Vlan), the speakers will reappear when the wifi is toggled with the Sonos app open. I feel I’m now being politely told to go away and no solution will be found. If anyone has found a solution I’d love to here it so I don’t have to constantly restart the app and/or force stop it.
