I've updated the plugin with what should fix the issue. You will need to make a change to a file in the Construct 2 CocoonJS export however.
In index.html, you will see:
<html>
<body>
<script src="c2runtime.js">
</script>
</body>
</html>
<html>
<body>
<script src="CocoonJS.js"></script>
<script src="CocoonJS_App.js"></script>
<script src="CocoonJS_App_ForCocoonJS.js"></script>
<script src="CocoonJS_App_ForWebView.js"></script>
<script src="c2runtime.js">
</script>
</body>
</html>
I've reached out to Ashley about getting that setup by default in C2 because I imagine that's breaking one or two of their plugins as well
