The .pbix download file in the Business Analytics Series > Find Your Top Customers Through Time Using RANKX in Power BI wDAX doesn’t match the video. Could you update the download to agree with the video or vice-versa? Also, when I try to make a copy of either of the matrices in the .pbix file the copy turns black and no data is displayed. Is this because it is an old .pbix and the matrix visual was in preview at the time?
