Noticed that in Windows 11 the Windows Security icon in the notification tray indicated there were some action to be addressed. The icon was a yellow triangle. However opening up the dashboard there are no action to take.
There is a good chance that the action is coming from the App & browser control section which may not be visible on the Dashboard. To open those settings open up the Windows start menu and search for "App" and select the App & browser control. The action needed should be listed in these settings.
