The Google Sheets add-on AutoCrat is set to run automatically at a specific time interval, when a form is submitted, or both. The add-on was recently updated and it needs you to re-authorize it to run on your behalf.
The add-on's automatic functions are temporarily disabled until you re-authorize it. To do so, open Google Sheets and run the add-on from the Add-ons menu .
This notification email will be sent to you at most once per day until the add-on is re-authorized.
