I found that I am just able to pull 300 latest raw data from Facebook Insight.
I am using Pro version and there was no problem to see all of Facebook Insight data until recently.
Is there any way to solve this problem?
unfortunately we are also suffering from a bug in Facebook's API which affects all external services that are using it, not just Supermetrics.
Facebook's development team is aware of the bug and they are working on a fix. We'll let you know as soon as there's something new about the subject.
We're very sorry for the inconvenience.
