How long after clicking Schedule Launch For Later before I get the option to create a teaser?

I've submitted my first product launch but I'm not seeing the option to create a teaser. All of the required data is present, and the launch is next Wednesday. The My Products page still shows my product as In Progress and not Scheduled? Does it need to reviewed and approved before anything else happens? When will it appear on the Coming Soon page, and how can I be sure it is actually scheduled? Thanks.
