the app is giving me the following error.
In handler 'savedsearch': Error while dispatching search
Just to add some context I'm running PANOS 6.0 and the latest version of the splunk and the app.
I have found a solution to this problem, which I have detailed also here:
I fixed it on our side.
In the "Overview" dashboard, click on "Edit" > "Edit Panels"
On the "Top Applications" panel, click on the first icon. I think it looked like a magnifying glass bounded by a square box.
Within that drop down, select "clone to an inline search."
This answer led me down that path.
