How do you display a situation where there was some data in the widget and then it disappeared? Is it possible that you had provided it but deleted it later?

It is possible that the widget is no longer available for this event. Whenever the widget link was provided in the beginning and then removed later it gets replaced with the "live stats not available" placeholder. The second way to confirm this is the DATA event. In the case where the live widget would no longer be available, we would send false in the DATA event payload. For more details, please see the Widgets documentation.
