Can't link my Echo Dot to my Alexa account using the Fios skill. Every time I try, it successfully logs in to the ssoauth.verizon.com domain, but then hits me with my challenge question saying it is an "unknown device." That would be all well and good, except for the fact that when I correctly answer the challenge question, it comes back with "The information you provided doesn't match what we have on file." I changed my challenge question and answer, tried again, and while the challenge question changed, it still wouldn't accept my answer.
Spent over four hours over two days with both Verizon folks and Alexa folks and they couldn't figure it out. Even more frustrating, Verizon doesn't seem to have a tech support team that is dedicated to, or even aware of Alexa, or someone who could see the SSO logs in realtime to see what was really going on. Net result was I kept getting bounced back and forth between Verizon and Alexa support, and got nowhere. I now have a ticket with "Enhanced Video Support" at Verizon, but I'm not hopeful.......
I'm not alone: based upon the reviews of the Fios Alexa Skill on the Alexa website, 6 out of 9 reviews posted in the last 4 days have the same problem. What gives?
