title: This add-on has created too many time-based triggers in this document for this Google user account
body: <p>I have a public google spreadsheet add-on that returns me this error <code>This add-on has created too many time-based triggers in this document for this Google user account.</code> when I try to add another trigger. I checked and the script does not have any active triggers.<br>
  Did someone else had this problem?  </p>
  
  <p>I see that there is also an issue posted here:<br>
