Try uninstalling the app and reinstalling it. (After the last update, on mobile at least, you should be presented with Sonos Ts & Cs to accept - if this hasn't been presented when you open the app, it might not have updated the app properly?)

Hi Rhonny and thanks for the reply, much appreciated. Yes tried that already before posting here and the existing system was auto-detected. Able to play albums from my ‘Sonos Favourites’ perfectly fine but unable to see the ‘Recently Played’ (see below)

I’m experiencing the exact same problem on my iPhone 15. Also tried to uninstall the app to no avail. Also can’t reauthorize my Apple Music account as a result. Super frustrated at this point. 

In your iOS, check in screen time and content restrictions for website. I could successfully load the login when I disabled content restrictions in screen time. I just reenabled them after.

thanks 

You could try Smartberry’s suggestion first because it is nearly harmless.

I haven’t experienced this issue, however, I have seen some users claim to have successfully worked through this issue by using Transfer System Ownership and simply gave the current account details for the new owner. Evidently, this worked through an issue at the SONOS account cloud server. It was not clear to me how this affected system details such as music service registrations, SONOS Playlists, and the local music library (if any). Recently Played, Sonos Favorites, etc.

I'm having the same problem. Any easy fixes?

C’mon SonoS - come up with the answer! I have a new iPhone 15 and as above, keep cycling through the Cycle of Death routine being asked to sign in as System Owner. 

Just FYI if you get this (‘Login as System Owner’) - you’re stuffed (to use a technical term).

You’ll have to factory reset every device on your SonoS network. The reset process is different for different products. You also have to make sure to reset the Sonos app as well when you get a flashing green light.

1. Open the Sonos app for iOS or Android.

2. Navigate to Account > App Preferences, and select Reset App.

3. Follow the on-screen prompts to reset the Sonos app.

Then add a speaker and setup a new Sonos system.

Did SonoS do any UAT when they released the latest version of their app? It doesn’t look like it.

I’m still having this issue - resetting App, speakers & transferring account does not work.

Sure hope Sonos knows they really screwed up on this one - releasing an unverified App - what a joke.

Like a fool, I actually purchased two additional speakers, I am stuck in the Login Loop of Doom on the App when I try to add them. I have them sitting in my office connected to my network by cat 6, they are functional, but the key part of the equation, actually being able to add them to the sonos app and use them is the defective part.  Tried the Reddit solutions google is full of similar user experiences. Is there anyone from Sonos prepared to give us hope on resolving this terrible customer experience?

Sonos systems are annoying and should never be recommended to ANYONE

I have purchased literally $1000’s of dollars of Sonos. This ‘ERA’ is so frustrating. I have tried calling and all the lines are “closed”. Sonos you are currently w***** status. Fix this issue.

I’ve got this issue, iPhone 15, any update on a fix?

Hi @Helpplease 

Welcome to the Sonos Community!

This issue was actually resolved back in August.

However, I have seen a few more reports since then. It does appear, however, that these reports seen in the Sonos app are now genuine - please note that it is now possible to log into any Sonos system with any Sonos account, but only if the log-in email is the same as the registration email will you be able to configure the system.

If the app is telling you that you are not signed in as the system owner, you likely are not.

As you have not filled in your profile for the community, I can’t say what I see (data protection), but if you own more than one speaker, then it looks like the email you are using here is not the same as the email your system is registered to. You may need to transfer the ownership of your Sonos system to your account (being sure not to make any typos as you do so). Please go to Settings icon » Manage » Transfer System Ownership » Continue to do so. Make sure your whole Sonos system is online in the app when you do so.

I hope this helps.
