Hi,
In our setup the "Last installed" tab does not reflect the actual status of our servers.This tab doesn't works as I was expected at first. At the beginning I was thinking that the date refers to the installation date. But in fact it is the date of publication of the package. I think this tab will disappear in WPP v2.
The report tab is empty...Ensure, you have selected at least one computer. At least, one update is approved in the ComputerGroup where the selected computer is.
