Am I missing something or is there no feedback during the review process of an App. We had one rejected which previously had gone through, OK my error on the app side, but it would be great to recieve an email from Apple say as much. It wasn't until the App had expired and users could not login that I was aware of the issue.

We have an App which will only be used by internal users. But in order to submit the app for review it is required to submit a username and password, but the app does not have this feature. It is basically a survey app to collect information and will not be available to the general public. Can a app be submitted without this detail.
