Please note that Facebook's API does not provide us with any data for posts that are over two years old.

This results in a few cases to consider:

Facebook Post is over two years old at the time the account is added to Measure.Studio.
​In this case, we are never able to pull data from Facebook on the post, so that is why these metric values are empty. We still allow you to see the post and group it though.

Facebook Post becomes two years old at some point after the account is added to Measure.Studio
​In this case, we estimate the post's daily data up to the day it was added to Measure.Studio, and collect daily data until it is two years old. After that, we are no longer able to collect additional daily data. Please note that it is extremely uncommon for a Facebook post older than two years to get any activity anyway.
