I am doing first the update.
For your information I edited the documentation and submit to you.
I found the 404 error in the console. In the network I have two others 404:
- jquery.min.map : /apps/studio/v2.0.6/vendor
- angular-route.min.js.map : /apps/studio/v2.0.6/lib
But map files are not required to have it working. You can add then to avoid the error but it is not a big deal.
