sign in as the system owner loop

Many people having this problem:

Im having same problem.  Ive had a sonos system for 7-10 years new components (sonos move) and sonos play 3 components and now the app is acting like it never met me.  I am the system owner and it keeps asking me to log in as system owner

Same very frustrating problem - the endless death loop of sign in as owner.

Me too cannot foe the life of me fix it

Anyone find a solution to this issue? Sonos?

Have you tried deleting the app and reinstalling it? It solves a multitude of issues...

I’d be tempted to reboot the router as well. 

If you want to, you could call Sonos Support directly to discuss it. They don’t inhabit this user forum. 

Same problem! Super annoying. Also have been building my system for a decade and up to nearly 20 Sonos products.  I love the sound, style and portability of Sonos, so I’ve overlooked the often struggling connectivity and backend fumbles and overall poor production and functionality of the App.  I also didn’t find any competitor product better… but I’ve been unable to make changes to my system in 6 weeks because of the App crash, so I’ve really been wondering how many Devialet speakers I can buy with the $$$ I will make if I sell my system.  Gonna try calling one, last timetoday… 

What issues are you having exactly?
