Microsoft have released another Technical Preview of Configuration Manager, this time it’s version 2201. Here is the official blurb. One of the cool new features is the ability to see the status of your content as it’s being distributed around your Global Infrastructure including both your on-premise and cloud (Cloud Management Gateways).
To see it in action, select Content Status
You’ll be moved to a graphical view of the sites where that content is targeted to. If you find that some of your CMG’s or distribution points are not showing up yet, then hit the refresh icon on the top right, I had to do it a few times before anything happened.
The Legend explains what the blue line and green arrow mean. After refreshing the page a few times it showed me the content in progress to my CMG.
