The problem has somehow magically disappeared!
My Question or Issue
I have a couple of Nest Audio's in my home and I am trying to play music via Spotify. After asking 'Hey Google, play some some music', then: 'OK Music on Spotify, here you go'. After a while: 'Sorry, something went wrong, when you are ready give it another try.' I noticed the same problem came up with older Google Home devices, but 'solution' (here, basically unlinking and relinking), doesn't work.
Anybody a solution?
