How do we get followers data in Facebook and Instagram?

You may have noticed that the followers chart has sometimes incomplete data for some date ranges.

This is because we get the followers numbers, for Facebook as well as for Instagram, each day starting with the day you add the page / profile.

Up until February 2018, historical followers data was available in Facebook for any competition page - but they closed that API endpoint for all apps.

So - if you don't see that chart yet, do not worry - it will come up in a couple of days, once we gather enough data to plot something.
