Interesting. As a guess, your controller (and device) is having trouble maintaining a good connection with your Beam, which is causing the ‘I’m here, I’m not here’ behavior.

Have you tried a network refresh? Or have you submitted a system diagnostic within 10 minutes of experiencing this problem, and called Sonos Support to discuss it? Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

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’d be tempted to try an update to iOS 26 as well, but that’s likely a side issue.

I’ll admit I updated both my iPads to iOS 18.7 first, in error, before updating them to iOS 26 (well, iPadOS, but to my mind, they’re the same)

Don’t know if you even use TruePlay; but are you able to run it on your iPhone using iOS26.0?

​@AjTrek1 , I use it in a couple of rooms, just not all (don’t find a significant difference, I’m relatively capable of placing speakers). Yes, I get the toggle and can get, at least to the opening screen, when trying to TruePlay a room, using iOS 26 on a iPhone 16 .

​@Airgetlam 

Thanks for the reply. It’s my iPhone 17 Pro Max that won’t run TruePlay as the Engineers haven’t mapped it yet. Just wanted to verify with someone who has iOS26.0; but not an iPhone 17.

​@AjTrek1 

Gotcha. And, for what it’s worth, I’m running this week’s (Monday? Tuesday? Don’t remember, but I suppose I could look it up) version of the Sonos iOS controller, S2 build 80.29.4 release (let me know if you want/need the rest of the numbers)

​@Airgetlam 

I haven’t downloaded the new version yet. Really hadn’t bothered to check. I’ll install it later as that may resolve/fix Trueplay for my iPhone 17 Pro Max. Will let you know.😊

​@AjTrek1 

I’d doubt it. TruePlay, as far as I’m aware, is toggled by a flag on a server somewhere, and isn’t part of the controller per se. Well, TruePlay itself is, but the toggle/access per device, I think, isn’t. 

iPhone 15 Pro running iOS 26.0.  with all the latest Sonos Updates.

No issue with Trueplay and ran in the last week.

I have had issues on the past where the Trueplay option was not available and that was due to one of my Roams being offline and not on the latest Sonos Build.  Turned all devices on (Move 2s and Roams) and checked for updates and it found the rogue missing update.  TP worked fine after that.

Thanks! I’ve since contacted support, and they discovered that no Trueplay configuration had been saved. I went ahead and re-ran Trueplay, which resolved the issue. It’s possible the config got wiped during a firmware update … 🤷

Not sure I understand how that’s possible, all of my TruePlay settings have stayed through many, many firmware updates, it’s only factory resets (which I try to avoid at all costs) that cause TruePlay to go away. But either way, I’m pleased yours is working again.
