Currently we are receiving Instagram data on a delay. This is due to a limitation that applies to the data we can collect, how frequently we can collect it and it has been limited by our provider.
We know this is not ideal but currently the data will be on a delay by a few days and you'll see the last day we collected it in the Instagram graph on the artist page.
Chartmetric Instagram Follower Analysis data is provided by SocialData.hk
It's important to know that SocialData have to go through millions of followers to detect notable ones, which means that the data is not instant or even updated on a specific schedule. Usually the audience analysis and notable followers will update once per month.
