It just resets the network/WiFi settings to factory - you would just need to setup the WiFi connection again. However I agree, if it’s happening on two devices that it may not be the answer, but strange it works fine on some devices on the same WiFi network, which infers it’s something related to the iOS device.

I have a 13 Pro Max and dark mode has always been fine within Sonos app since it first launched, even with 15.3 update today.

Works under both system default appearance mode and Dark Mode options in the Sonos app, but that’s no use if the OP doesn’t have the Appearance option visible in the app.

OK on my ipad pro but option for dark mode on my iPhone 13 pro has gone 

Both running 15.3 diagnostic number 912037269

Maybe reset the iPhone’s network settings and then setup the WiFi connection again. 

Reset your controller and reconnect it to the ‘existing system’ when it restarts. 

Dark mode is enabled by a feature-set definition stored in the cloud. If the server is unreachable (or offline obviously) it may not work. A DNS filter could be a possible culprit. 

Hiya,

just tried it and it made no difference

will just have to live with it

Just to rule it out as a possibility, can you uninstall that profile, do some testing, then reinstall it?

I used to have occasional issues with the profile I was forced to use at a former job, where it would block some traffic, seemingly randomly. I’m sure there was a reason, I just never could figure it out, and as you have suggested, I just lived with it. 
 

I’m more curious than anything else…completely understand if you feel it’s too much effort. 

No, not using google WiFi.

Dark Mode has now returned on my devices.

I restarted an iPhone and iPad for it to reappear, then just force closed the app twice on another iPad, as first time was unsuccessful (although these same attempts were unsuccessful a few hours beforehand)

Hope you have some joy @BMF getting it to work again

Same here. iPad still has dark mode but both my iPhones have lost Dark mode in the past hour. The option in the app settings has also disappeared on the phones. All running iOS 15.3 and the latest Sonos S2 v14.0

Hey @BMF,

This can happen if your iPhone is unable to connect to one of our servers in time. A diagnostic would let us confirm that, but I’m glad that darkness has returned to your device 

Please do let us know and attempt to grab a diagnostic if this happens again.

In an earlier reply, Staff mention the need for the App to be able to connect to one of the Sonos servers. Are there any security Apps on your mobile(s) or firewall on the router etc; blocking connections perhaps? If so maybe see what happens when you switch off those features temporarily and try closing/opening the App fully (once or twice) to see if the feature shows up in the App under ‘Settings/App Preferences’. 

Thanks for that.

Looking at the diagnostic, I’m not seeing any specific errors in connecting to the server, but there are some network timeouts when launching the controller.

I’m not quite sure why these are happening, but I did happen to notice you’re running iOS 15.2, which I believe is still in beta. Since we can’t officially support beta software on controllers, it’s entirely possible that there’s something in this version causing this issue.

Do you have any iOS devices running 15.1.1 (current at the time of writing) that are experiencing this problem?

Hi @James L. 

will check on my wife’s phone as she will be running the latest “official” iOS.

Odd thing is, my iPad is on the same version as my iPhone and does not show the same behaviour. 

will report back 

Huh. Just opened up my S2 14.0 on both my iPhone 13 running iOS 15.2.1, as well as my iPad Pro (11 inch), which is running iPad OS 15.2.1 , and both are operating in dark mode.

Let me download and install 15.3 and see if I can reproduce this :) 

Which iOS device are you using? 

Edit: Is it just the Pro Max that you’re having issues on, or all iOS devices?

Hi @James L. 

ahh, ok. Thanks, 

If I see it again, I will grab a diagnostics report

It’s really odd, I don’t have a firewall or parental control as such.

I do have nextdns that filters trackers… BUT I have tried using Google DNS and cloudfare which do not do any filtering.

I could not see anything obvious in the nextdns logs that record the requests that are made…. Which is why I tried Google DNS and cloudfare, but is the same no matter what dns I use.

I have tried force closing the app many, many times, reinstalling etc.

Hi Ken, as it is on both iPhone and iPad, unlikely to be that.

Will have to see how that is handled these days, I think it has improved, but it used to a fairly nuclear option that took ages to get things back.

Just happened again….

diagnostics 678727555

Yes, rebooted phone many times … everything has been rebooted during tests.

Did you try rebooting your mobile? 

Tried that several times, just tried it again….. no difference 

I have tried 3 different DNS services, Google, CloudFare and NextDNS…. All behave the same way.

Also, my wife is in the same network with the same DNS servers and it works fine for her.

really strange
