My "Summary Report" stopped showing IAP items on the weekend. The "Content Items" section used to IAP items also. To get to my IAP statistics now I need to click on the free published item and then click on the IAP item there. I'm hoping that this change isn't permanent because my IAP items are the most important to me.
Edit: I've worked out how to get back to where I was. If I click the "all time" button for the time period then I get back to the screen that I'm used to.
