Eliminación masiva

Hola, ¿Cómo puedo eliminar por ejemplo todas los envios de una encuesta de 2018?

Are you referring to the form submissions to be deleted from a form? If so, please refer to the guide below that can help you with this.

Please note that the deletion of submissions is a permanent action and the deleted submissions cannot be recovered in anyway. If you want to take a backup of the submissions, you may export the submissions from the Data section of your account settings.
