Hi

I have the same iPhone running the latest iOS and my Sonos is S2 on OS 16.1. No issues.

Please describe your network in detail as this is most likely a network issue.

The app is fine.

Make sure the Sonos app has the “Local Network” permission. (This option does not exist on iPads).

Make sure you don’t have a VPN enabled on your phone.

I've been experiencing connectivity issues with my Sonos system since returning from vacation. Prior to leaving, my iPhone seamlessly connected to the system, but now it's unable to do so. Despite ensuring that the Sonos app has the necessary "Local Network" permission and that there's no VPN enabled on my phone, the problem persists.

My Sonos setup includes four One speakers, a Beam, and a Boost, all connected to the local network (Boost via cable, others wirelessly). My network consists of a main router and one WiFi access point. Considering these details, it seems likely that the problem may be related to either the iOS version (17.4.1) or the Sonos app's compatibility with it. I've tried various troubleshooting steps but haven't found a solution. Could you please advise on how to resolve this issue? Thank you.

Additionally, it's worth noting that there are no issues with an iPad running iOS 16.3.1; everything functions correctly within the same network.

Are both phones connecting to the same access point and band 2.4/ GHz?

Can’t help you on the versions question past the Sonos FAQ link,

I can without a doubt rule out the iPhone iOS and Sonos app version as the problem areas. Especially so as you say there are no VPN’s involved. That said...there’s definitely a network issue.

As you are using a Boost all Sonos should be using the SonosNet. Try removing the WiFi access point to see if the issue is resolved. If it is...then you have your answer. 

BTW...it doesn’t matter if the access point was installed months or years ago prior to your issue manifesting itself. Updates may occur in the background that can change a networks behavior. 

Yeah this is for sure a local network problem, but the OP hasn’t provided any details about it so further speculation is difficult.

There’s a problem with the latest version of the App … I wish Sonos would acknowledge the problem and get on with the bug fix - rather than leaving users to try to figure it out themselves.

Totally agree with RCWelwyn,

Something's changed in the configuration of the Sonos app - combination iOS17.5.*, almost impossible to manage my sonos playbase settings from my Iphone 15 Pro since a couple of weeks which is very annoying, no problem using the app from our older Ipad. Hope Sonos can solve the issue.

Regards, Danny

Manage is a very vague/broad term. Just exactly what are you having issues with regarding your Playbase.?

AjTrek1 - Agree, to be more specific; Sonos app Iphone 15 pro » System settings - System - Sound settings;

Trueplay - EQ and volume limit        opens with “default settings”, not with the actual settings of my playbase. (which i can manage from our iPad)

Sometimes when i open and close the Sonos app maybe 5 times, it show the real actual settings but then again changes aren't saved.

What iOS version is the iPad using? Also, what version of the Sonos app is on the iPad?

iOS version 16.7.8  diagnostic info app send with code

Moderator Note - Removed and recorded diagnostics number.

The iPad is running an old version which explains why it may be more stable. However I’m running the latest iOS on my iPhone 15 Pro Max with no issues. I sent you sent a diagnostic. Hopefully you sent it for the iPhone or maybe both. In any event you must now call Sonos Tech Support to discuss the findings. They should be able to take over from here. Good luck to resolve the issue.

I have exactly the same problem. Moved from an iPhone 13 to an iPhone 15 Pro Max and my system (Arc + 2 One SL + Sub) is not reachable anymore. A Macbook and a PC with related Sonos App are connecting seamlessy to the SOnos system. All very annoying. Tried everything.

Hi again. I have actually solved the issue. In may case the “invisibility” of my Sonos system was not due to a network issue I but rather to the fact I had a beta IOS version on the iPhone. Once downgraded to the latest official IOS version (17.6) the Sonos app was immediately able to find the system and operate normally. May worth to add to the troubleshooting and hope may help others.
