Hi Gyumin, Formfacade supports only public forms. You must disable Google forms features that require sign to use your form with Formfacade. You have enabled the collect email addresses option with verified input settings. This feature requires users to signin to view the form and submit their response. Open your form in Google Forms > click Settings > click Responses > select Responder input instead of Verified input or select Do not collect and add a short answer question with email response validation to collect email address from the respondents. Once you make this change, click on the addon icon > click Formfacade > click More options > click Customize to sync the changes with Formfacade > Formfacade Edit page will open in a new tab > click Responses > In the Responses page, click on the three dots icon next to the Submitted status > click Email Collaborators > setup wizard will be displayed > Enter the email address and click Next > update the subject and click Next > update the message and click Next. Whenever a user submits a form, the notification email will be sent to the configured email addresses.
