I have 2 Facebook Insights accounts setup in my Supermetrics plugin for Google Sheets. As of the last week one of these is now only allowing me to pull the last 14 days worth of data, where as the other appears to have no restrictions on it.
Is there any insight or suggestions you have on how to open up this date range greater than 14 days?
FYI...I am having the same issue. See the response on my ticket: https://support.supermetrics.com/support/tickets/7028
Unfortunately there is an issue with the Facebook API at the moment, limiting the amount of posts returned in the query results. See https://developers.facebook.com/bugs/2297783020445879/ for more details. We'll let you know as soon as there's more information from Facebook in this matter.
