Didn’t get the message you mentioned. However, I have confirmed via the moderators that the iPhone 17 hasn’t been mapped as of yet by Sonos engineers. Hopefully, the issue will be resolved sooner than later.

Sonos, and other manufacturers, do not have access to a new iPhone prior to its release. This is due to Apple’s policies. Once a device is in the dev’s possession, they can then begin to update the app for the new hardware. This includes the microphone, which is going to be different from the pasts generations. 

In the past, Sonos has made the changes and released an update by November. It may be sooner, but don’t get your hopes up. 

Based on past experience, I wouldn’t expect Trueplay to be available on the latest iPhones until December.

Both iPhones 13 and 14 were mid-December, with iPhone 15 around 1st December.

The unsupported Trueplay-compatible devices hasn’t even been updated to include the iPhone 17.

I have an iPhone Air and an iPad Air M2, both of which are experiencing the same problem as you.
I get the message "Trueplay is not compatible with your device." and Trueplay does not work.

The iPhone Air is too new, so it will take a couple of months if indeed it is eventually supported.

The iPad Air M2 is listed as an unsupported device. The majority of iPad releases now are not supported for Trueplay, so I wouldn’t buy a new iPad with an expectation of running Trueplay [Advanced} on it at any point.

The iPhone 16 still isn’t supported , I tried when my gf ordered a Beam, neither my 17.

my iPad Air 5 works thankfully

anybody able to use iPhone 16 ? Surly that should be working by now ?

Happy to report that TruePlay for iPhone 17 running the latest iOS is working after the latest Sonos Updates. As stated in the link below everyone may not get the updates at the same time as it’s a phased roll-out.
