4. Save the updated manifest and upload it back into Windows Azure using the same Manage Manifest button in the footer (select "Upload Manifest" this time)

   Info
   Note: If you try to download the manifest again, you'll notice that the expiration dates are now there and the cert value is now null. This is normal and it shouldn't prevent the app to work as expected.
