title: Unable to test facebook messenger bot. Webhook not receiving events
body: <p>Following the recent changes for facebook developer, i had this alert on the webhook section on the developer dashboard, and therefore no webhook messages are received from 'testers, devs, etc' ;</p>

  <p>As a result i am unable to test my mesenger bot apps. 
  I have created "Test users" from the "roles" section;</p>

  <p>When i login with any "Test Users", the messenger bot app created does not appear in the Messenger Bot search.</p>
  
  <p>Kindly note that my initial Webhook subscription at the developer dashboard is successful.</p>
  
  <p>I want to test the bot before submitting for approval, is my approach wrong?
  I am really at a loss as how to proceed. Any help will be very much appreciated.</p>
