Reboot the Controller of force-kill the App as a first step.

Remove and reinstall as a second.

You might also want to check and insure all Sonos are on the same software versions, under System - About.

​@Talkien,

It does look quite like the Sonos App was updated, but that the firmware on the speakers/products perhaps needs updating too (or vice versa) as ​@Stanley_4 mentions above.

Couldn’t agree more talkien. Sonos you’ve done it again!!!

how can you get it so wrong….

Stanley, 

thanks for your reply,

checked the sonos devices and they are all on the same version :16.5.1 ( build 82.3-60160)

App was the latest in they app store, removed it, and reinstalled.

Unfortunately this didn’t work.

gave all sonos a power cycle, what did have an positive effect.

I look forward to an system that doesn’t need monthly/weekly action to keep it functional

If power cycling your devices worked, you may want to check out my post:

The static/reserved IP addresses trick solved my severe stability issues.

See your router’s DHCP settings page to do that.

More info please…

barton: Your router should have a help screen on the DHCP settings page to guide you through the process. If you can’t find it post the router’s brand and version and someone here could try to find the user manual for you.

Usually you just open the DHCP page and see a list of your devices, select a Sonos one and give it an address. The router usually tells you which ones are available for use.

Thanks for your help Stanley. I’m all good with setting up the static ip’s. Did you do this for each Sonos product you have?  I’ve got 20+….would that be 20+ ip’s to set up?

I feel your pain, I have 21, but not doing all of them probably won’t hit all the instances of the IP issue.

I took the time to give them pretty (to me) names too.

Thank you very much for your time in replying Stanley. I’ll definitely try this out in bite size chunks. Interestingly this was never a noticeable issue prior to app upgrades etc. cheers

They changed a lot of stuff under the hood with the updates, not all is working as well in the real world as it did on the test bench.

Ever since the update this week my 3 Sonos One’s doesn’t work at all. Please fix the it worked fine before the update

The Sonos Ones seem to be fine here, maybe try a reboot of the players and a further check for any firmware updates.
