If the reach and engagement metrics you’ve seen on your Facebook page seem a little off, it’s because there’s been a bug affecting those figures. Facebook admitted to many page owners today that there is a discrepancy between the reported reach admins see on posts and the actual reach and engagement of a post.
Many page admins can see this message atop the dashboard:
There is a discrepancy in the engagement and reach metrics for all Page Posts and Boosted Posts between 5/30 and 6/30. We are working to resolve the issue as soon as possible.
