Listing traffic history

For anyone having issues with their Listing Traffic History:-

 

On my Listing Traffic History page, I am currently only able to see the number of views my items have had.  There is normally a 'pointed' graph on the lower half of the page with the 'points' indicating the date(s) of these views .  This lower half of my Listing Traffic History page is currently blank with no graph.  I have just spoken to Ebay to report this and have been advised a bug/glitch appeared in the system yesterday - 21.4.26.  Ebay said UK and USA customers are experiencing this problem.  Ebay said they are working on it.
