Global page likes are public knowledge and do not require special page access. Starting in 2018, regional page likes require a first-party token to access them. TrackMaven cannot collect data for regional page likes unless someone with access to that Facebook page has authenticated it in TrackMaven.
The platform does not allow users to see regional page likes for a regional brand in reports unless their workspaces have first-party authentication for the regional pages. This restriction ensures that your competitors cannot access regional like data.
