If you are still logged into your client account and click on a widget you've created, you'll see an error that says, "Sorry, your membership type does not allow access to widget titles"
Client accounts cannot be pre-approved to view titles. In order to view the widget in action, you must be logged in to a reader account. If you want to test the widget before sending to your contacts (which we recommend), create a reader account here (using a different email address than what you have listed in your publisher account), or send the test widget email to concierge[at]netgalley.com so we can test it for you.
