I had my project working fine (http://codepen.io/JKatras/full/aNRbXw/), until I happened to check it today and all users are shown as not existing now. Checking some of the older projects on CodePen, it looks like a lot of people are having the same problem.
I don’t see any error in console except
Uncaught ReferenceError: $ is not defined - contentscript.js:21 which seems to be on CodePen’s side.
Does anyone know if something changed with the Twitch API?
