Traditionally, Action center messages were loaded starting with the oldest notification for the user and iteratively over time retrieving newer messages. With this approach, it could take a long time for users to see the newest and most relevant messages since the user last logged in. This feature optimizes how Action center messages are retrieved by simply loading the 100 newest messages. Users can select "See all" in the Action center to browse or filter through older messages. New messages received while the user is logged in will continue to display in the Action center.
