Page Level Security

Hi, I set up a sort of "page level security" using the below steps. 

Step. 1 Create the message to display as card visual

DisplayMessage = IF(HASONEFILTER(Staff[Director?]),"Oops, sorry you are not authorized to view this page","")

Step. 2 Add this to create a white or transparent background on the card

Make Transparent = IF(HASONEFILTER(Staff[Director?]),"#White","#FFFFFF00")

Step. 3 Set up Row-level security.

The goal is if the user is not a Director, display the message "Oops, sorry you are not authorized to view this page" Otherwise, allow access to the page as per the user's Director status.

It seems that this is not working on the PBI service. Please find attached PBIX sample file and thanks in advance 🙂
