When you start Kodi do you a see a pop up message from the add-on that says it has connected?

Yes, I get the "Kodi Connect Connected" message slide in from the top right of the screen when I start Kodi.   

Just tried Linking again and still get the "We were unable to link Kodi at this time." message. 

Something I just noticed now is that the first time I click the "Alexa Beta Test" button and click on the "Invitation Url" Link I get the following message:
Safari can't open the page "https://spa/index.html?fragment=skills/ypur-skills/tvt/....(a bunch of letters and numbers...) because Safari can't find the server "spa".

However if I close that tab and go back and click the link again I get prompted to Login to Amazon Alexa and try to Enable the skill, which fails.

Does getting the server error first have something to do with it not being able to link? If so any ideas how to fix?

Still searching for answers here....
