School says they didn't receive my application

 The confirmation page you received is the verification that your application was submitted successfully. Depending on the system the school uses, it may take a few more days for the school to upload your information and add it to their system. Often that does not happen instantly, so you should wait a few days before checking with the school about a submitted application.

To access your confirmation page, navigate to the Colleges list in your StandOut Admissions Network account and click on the "View Submission" button.

The form verifies the time and date of your submission as well as shows a payment receipt.
