I can fill and go down in the form using tabs, but when I click submit nothing happens.
Chrome developer console shows it returned 405.
Thanks for bringing this to our attention! Sorry for the inconvenience for the time being. The team will try to fix this soon, and we'll update this thread.
Sorry for the wait, but the form is now back up and running!https://dev.twitter.com/ads/ads-api-access-developerCarmen
