More for the My Esri site than ArcGIS Online - but I wish license updates and changes were listed on the My Esri site for admins! Maybe a link on the menu that goes to a list to all the blog posts/documentation to show all communication and correspondence for the license changes and updates.
This way - it would be a one stop show for all admins to be able to see license updates. Versus searching through documentation or blog posts individually.
Thank you!
