Google... cmon guys. This has been an issue since Sunday and we haven't
gotten a "hey yall we are working on this" message. We paid a lot of
money for these devices.
I am having the same issue. I added the first Nest Protect and now my
second goes through the entire process and then says "Failed to add Nest
Protect to account". I have reset the Nest Protect and tried the setup
process numerous times. Same result ...
