During the setup, after selecting the room the linking to account keeps failing.

I hear the audible PIN and press the button in the back, but it still keeps failing.

I have tried all the usual drill steps of restarting phone, router, hard reset the Sonos one, removing and reinstalling app, using another phone and such. I have also connected it directly to router via ethernet. Still no luck. 

I have 5 other sonos products (including one gen2) that are on my wifi network and working fine which makes me think that the wifi network itself is not an issue and I set one other device up as recently as 5 days ago.
