The content amount required in order for the Blue Orb to not display varies based on the screen resolution and the size of the user's browser window or device screen. There is no standard for how much content is needed in order for the orb to not display.

For Example: If you only have 2 items displaying in Recent Activity. This content does not fill the browser window on a computer, and the loading icon (blue orb) will display infinitely.
  • If you shrink down your browser window or click the 2 items in your Recent Activity to expand them, then the blue orb stops displaying, and you get the following message: You have read all the content in your activity stream.

Note: Sometimes, recently enabled public content (such as a news content type) in your Recent Activity board  will cause the blue orb to populate instead of the content. 
Before the recent activity will populate, you will need to either:
  • Edit one of the existing items and save it again
    OR
  • Create a 'new' item
