When you first sign into the Questra IDM Application Suite, the window defaults to the Group view of your default group. (If you own multiple groups, one will have been defined as your default group.) All of the information you see on the Content pane pertains to the devices in the default group. On the Action pane, notice that some actions are not available because you have not yet selected a specific device to work with.
