Currently it is not possible in Feedlync to download the data as excel, csv or pdf, with the dropdown.
You can see the data in the dropdown on your screen, but you cannot download it together with the main table.
As a simple example: The purple fields are not downloaded when trying this screen as a csv file. Only the 2 main rows are visible when opening in excel.
(The goal is not that this should be the default settings, but it would be nice and easier for our customers, if we at least have the option.)
