Yesterday i poosted the same question , but i accidentally clicked on Accept as solution. I have created a desktop report with two different graphs, published to a workspace and then updated the app. In the report i see the changes that i made, but when i click on the App the changes seems to be made only one graph. Please see the attached screen shots.
The first one is from the report (i made the sort on the "File Year" with the current year at the TOP, but the changes not made in App for the tree graph (Second image).
