title: Missing Authorization in Google form submission
body: <p>I have google apps of form, when response save in spreadsheet, it activate a script to send an email to a user. After running 4 months, today I got an error message through script response:</p>
  
  <pre><code>Details:
  Start   Function    Error Message   Trigger End
  11/10/16 10:49 AM   formSubmitReply Authorization is required to perform that action.   formSubmit  11/10/16 10:49 AM
  </code></pre>
  
  <p>I checked "Connected apps &amp; sites" of "sign-in &amp; security" of "My Account" in google. It registers 7 my apps but not the error apps.</p>
  
  <p>So, I want to ask how I can activate the missing apps in authorization list.</p>
  
  <p>Thanks in advance.</p>
