From May 10, 2021, Cervinodata collects Facebook Ads data on the ad group (ad set) level. After collection the ad group data is aggregated to the campaign level.
This is because of the fact that if data is collected on the campaign level, attribution related data for a certain campaign is left out by the Facebook API if there are multiple (as in different) attribution settings for the ad groups belonging to that campaign.
After the data has been collected and processed, you can view your data via the two Cervinodata Google Data Studio connectors that are available specifically for Facebook Ads Ad groups:
And also via the default Facebook Ads (Campaign) connectors:
Or you can view the data in Google Big Query after setting up a GBQ connection and synchronising your data to GBQ.
