The Google Sheets add-on is set to run automatically whenever a form is submitted. 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. Alternatively, you can click this link to authorize it:

Re-authorize the add-on.

This notification email will be sent to you at most once per day until the add-on is re-authorized.
