I signed up weeks ago too. Same issue, nothing happened. I thought there was kind of issue with the feed or something, so smailed their support a week+ later and basically got told to try reinstalling the app again. I did ask for clarification on whether our store had been approved yet, as I thought perhaps this was the issue, but they never responded to that question.
Emailed their support again a couple more weeks later and have since had no response for over a week now.
