Thanks for the quick responses.
So I clicked on the gear to the right of SP2 and it took me to a page that's entitled "Configure Service Provider Accounts". Below that title is a list of service providers, including Anveo, followed by a link entitled "Generic Service Provider", which is what Anveo's setup page says to use.
I tried setting up using the "Anveo" link, then again using the "Generic Service Provider" link along with Anveo's recommended settings, and both times, the page returned the error code "Register Failed: 400 Bad From URI".
Is there something else I can try before I move on to the expert configuration mode? Will a factory restart help?
I wonder why this isn't as simple as setting up GV was. Thanks again.
