Can't register new Client ID on Instagram developers page

I used the Content-Security-Policy extension for chrome.

https://github.com/PhilGrayson/chrome-csp-disable

Then the field appeared -> New App Created.

The form is broken.

I've been trying it on and off for the last two weeks, also with different browsers, it doesn't work.

I have exactly the same problem when trying to create an client ID. I've send in a ticket for a solution.
