I'm trying to use the Report function to show the result of a workflow in a Pie chart. I've followed this video:
step by step, but when I click on "Finish", the Pie Chart appears for a few seconds and then it disappears. It seems to be something, but I can't show it. Plus, the report items icons are gray, even the report icon.
As attached, I include the workflow and an Image to show the result of report.
