Hi rcards,
The latest instructions I have read do not cover the new Google Developers section, do you also have an updated manual to follow the process that Google requires you to follow?
Are you referring to these instructions?

It says at the top "Below are shown screenshots from both the old and new control panels" - is the "new Google Developers section" different to both of those?
