Hi Alex, when you customize your form using the Formfacade, the service account email is added as a collaborator in Google Forms so that you can make the edits directly in Formfacade. If this fails or if you manually remove the editor service account, then a warning message will be displayed when open the form in Formfacade. Open your form in Google Forms > click on the addon icon > click Formfacade > click Customize this form > click Proceed > Formfacade Edit page should open in a new tab > You should be able to make edits in your form. If you face any issues, please send an email to support@formfacade.com. We can do a screenshare and check this.
