Since the weekend I'm seeing regular red banners listing unsupported OS in Central. I do have a handful of these Win7, 2008 etc so expect to see these alerts when I login to Central first time each day. However, even though I dismiss these banners they now appear again every few minutes, I'm unable to dismiss them permanently for that session it seems!
Have tried Firefox & Edge but these banners keep appearing. Purged Cache but made no difference, the banners keep appearing every few minutes.
