We've added a new metric, Follower Change for an individual Post, Story and Tweet. This metric shows the change in followers on the account in the first 24 hours the media was published.
It's available only on the plans with the "Hourly Updates" feature: Gold, Platinum, Agency plans and free trials.
Historical data is not available for this metric. Customers with an active subscription will have this data available for media published since 25 Feb 2021.
