I'm struggling to create a dynamic group to identify out of date agents from where I can force them to update to the latest version. I know from the dashboard that I have 91 devices with an out of date management agent but no matter what I try I cannot create a dynamic group to show me these devices. Here's a screenshot of the settings I currently have and this shows me 1 device with an out of date agent only. Please if anyone has any suggestions.
