I also had to add more details to mine after the first submission, it is waiting for approval again for about 5 days. I think so many users are trying to get an app to publish the devs are just behind on approving them.

In case of delay, you can send your request through email and ask them to review your request. You should also include the client id of your application in the mail.

Our team is still reviewing your app. It takes longer normal approval time because your app is concerned about SMS regulations. Please be patient and you will be contacted by the team via email about the approval result.
