Once your build is selected, and all your App Store listing data is filled out, you may click the "Submit for Review" button in the top right. On the next page, you may be asked questions about Cryptography, the Advertising Identifier, and 3rd Party Content. GoNative apps DO use Cryptography, but fall under the exception for standard user authentication. GoNative does NOT use the Advertising Identifier. You will have to determine for yourself if your app uses 3rd party content, and if you have the rights to it.
