Appstore SDK Troubleshooting

This page describes how to troubleshoot issues you might encounter in your app when working with In-App Purchasing (IAP) or DRM from the Appstore SDK. If you're having issues when making calls for IAP or DRM, check the device logs for the following errors.

  2. Go to Apps & Services > My Apps. Then click your app.
  3. Go to the Upload Your App File screen.
