The latest firmware and app update did resolve that issue for some user (including me) but sadly not for all. I just can tell you, that Sonos still is aware of the problem and is working on a solution.  

The worst software update in my life. Loved Sonos, planned to buy more but after this I will never buy a single piece from them

Unfortunatelly , you are right . I have 6 Sonos devices . On this issue I come to know , that Sonos do not take care of customers , and they can easily "block" products. In the past I worked as software developer , so I know , how it works. No way , to not to be able  repair software bug in 9 monhs !!. It is about minutes , maximum about days . Not nearly a year !  Luckily my Sonos start working few days ago. AS I wrote here I had lastest firmware and latest app already long time already, and it doesn't help. Meanwhile I installed app on Windows desktop , and try to reathorize frome there. It doesn't help. It starts working "alone" after few days, after I wrote here. I think , they are manually correcting one by one , when somebody complain !!!. 

Unbelievable.  It works for me 4 days. Yes four days !! Such **** system. !!!! Do you want to tell me that I throw more than 2000 Euro thru window?

Yeah! Moderate **** content but not solve the real problems! Reauthorize does not work on iOS/iPad…

I’d think the people who moderate these boards do not have the same job as the coders who might be able to change the code to ‘fix’ this issue. Much as probably the folks at Sonos Support, who you might get assistance from when you call in, but equally are not coders.
