No system and repeat log in requests

Hi. I own a Sonos Arc, Beam, and 2 Sub Minis. All were purchased recently and working fine until all of a sudden the IOS app continually asks for owner log in and I am the owner! Also if I click on System it says no products registered. Everything is on the same network with the same email address and password. I have tried deleting and reinstalling the app all to no avail. I have tried logging in on Sonos .com on my Mac and still  no products registered. It seems that the Sonos app is not available with the Mac OS so I am unable to try that option. I have reset and the Sonos app on my iPhone which is running the latest software update. I have Signed in and out many times and deleted and reinstalled the app. I understand there was a recent update to the app which has caused a similar problem to lots of frustrated owners...including me! Are Sonos going to fix this problem? My two Sonos systems will still play Apple Music and audio from my two TV’s but I am unable to access any of them on the IOS app or access Recently Played either, just keeps asking me to log in as owner of system!. Any advise to how to fix this please?  I paid a lot of hard earned cash for these Sonos products and want them to work properly. Thanks
