So I did spend the last 2 1/2 hours with both Amazon Echo & Apple support. Amazon and I walked though everything including once again logging in then logging out. 2FA etc... basically everything. They told me to call Apple.
I did. Apple spent over an 1 1/2 hour on the phone with me and we checked everything. And, with Apple monitoring my screen as we looked, verified everything was perfect especially since all my other devices were syncing perfectly with iCloud.
Apple suggested I call Amazon support back while they remained on the line. I let Amazon know I had called, the problem, the (non)result and that apple was on the line.
Response:
Amazon: Apple is on the line sir?
Me: Yes
Amazon: Click
Bottom line is that this really appears to be an Amazon echo problem and they seem to like to, or care to trouble shoot too much with real technical folk.
Still not working.
