What does "The LiveArea screen has been refreshed" mean?

When I come back to my PS Vita occasionally it will have 1+ notifications that "The LiveArea screen has been refreshed", usually for the Videos and Store apps.

What does this mean? Does some setting control this?


Solution 1:

This indicates that the content cache powering the LiveArea UI has been refreshed. For example, when this happens, information about PSN and its available content is refreshed (amongst other things, like the video store).
