So, no matter what I do, I always get the message "Your code is invalid. Make sure you entered the code displayed in Kodi and you're in the same network as your kodi device," every time I try to authenticate. I have used three different devices (including the my Kodi device), and multiple wifi networks.
UPDATE - I figured it out! It was a problem on my end!

 What was the problem you encountered on your end?  I've run into the same issue with the invalid authentication code.  Thank you!
