- speleding 7y agoThere are perfectly valid use cases for third party cookies that do not involve tracking. Our business offers an appointment scheduling widget, it needs cookies for user sessions, and those cookies are third party because the widget is commonly included on a web page inside an iframe. That widget now breaks in the new safari preview.
