After the transition to Global Pages, it will take a week for insights to accurately reflect the Pages in their Global Pages structure.

However, the insights are not retroactive. This means that if a brand transitioned to Global Pages in March 2015, the brand viewing their current insights will see the same insights that they would have seen in January 2015.

Both default and market Pages will have their own insights. People managing the root Page can see insights about the fans aggregated across all of the Pages.
