macOS controller in update loop (16.1)

Having an issue with the macOS Controller on my M1 MacBook Pro since the 16.1.1 install a few weeks back.

Whenever I load the controller it says ‘We need to get Sonos running on the latest software. Choose Check for Updated to get started.’

I press Check and it comes up with ‘No update required. Your Sonos system is up-to-date.’

I have deleted the app and reinstalled. I then deep-deleted the app (from ~Library etc) and reinstalled. Same issue.

The app and updater has permissions to update under Security > Privacy etc.

If I press ‘Continue using the SONOS app’ it then goes to searching and then puts me in a similar loop which is

‘Some of your products aren’t registered to your Sonos account. Let’s register them now so you can use them’.

I log-in and it goes back to ‘No update required.

Can anyone suggest what to do now? I’ve tried ‘Reset App’ etc too.

thanks
