Great insights @paulag. I had worked on PowerBI couple of months ago. I have a couple of hunches that I want to validate with data. So I am planning on opening PowerBI again. I am on a MAC and looks like there is no app for MAC. Do you do all your analysis on web version or a desktop version??

Also could you guide me to a good tutorial on DAX queries? Thought I have used Excel formulas and queries I think I need to brush up on my DAX.
