No data about last refresh date in PowerBi Service

Hi ania_roh ,

What is the connection mode of the report? 

Only import model will show up the updated date. It means the dataset on power bi service has been updated at that date.

Because when the dataset is Direct Query or Live connection model, the power bi does not refersh the report until user view the report or active with it.

If DirectQuery and LC show up the updated date, it will be every time user open the report, becasue power bi service query the data sourece, not in power bi service, to get the underlying date and calculate the data for visuals.

Please refer this article.
