To edit a Form, it must first be deactivated. This can be done by viewing a Form in the ‘Forms’ screen. In the following screen, you can deactivate the Form.
In the ‘Forms’ screen, all deactivated Forms will show an ‘Edit’ button next to the URL. This button can be used to edit the Form.
It is not possible to edit the URL itself. In case you do need a different URL, you can create a new Form.
After editing the Form, you need to reactivate the Form so it can be used for submissions.
