There was originally a bug that caused the submission process to not complete properly (meaning you would not get the email). However, this should be fixed now. If you never got the email I would recommend going into Share and making sure it hit the submit button to complete your submission.
I would recommend going into Share and re-submitting your app. Once submitted you should not be able to edit your entry and you will receive an email confirming the submission of your app.
Have you tried email [email protected]?
We had submitted in mid September and had not heard anything, so I emailed them a couple of weeks ago and received a very quick response (that is when we found out our app had not been submitted).
