G'day jmlozb, was wondering what the outcome of this was? My Nest Audio
started having issues recently, much the same as yours. Managed to reset
it and it worked for a few days then it got completely bricked (doesn't
even seem to turn on). Google sup...
The same thing happened to me. Around 1-2 weeks ago we had the 4 dots
randomly. After a few restarts and holding the reset it started working.
A few days ago our Nest Audio doesn't seem to power on now. I'm raising
a support ticket.
