FYI, I got the same questions, filled it all out, linked and unlinked
(again) and referred Teddy to this thread. They should just get a
speaker and a subscription to SiriusXM and try to stream an Xtra
channel.
I'm working with Teddy from the Google Nest Customer Care Team. I've
answered questions via email and this is where things stood as of
10/30."I got your email. Allow me to check these details and I will get
back to you as soon as possible. "
