Do ALL of the downloads recorded count against the folio allocation (for pro account)? Even those downloaded through dev viewers?
Folios download from Distribution Server are recorded as Folio downloads, they may be the published folios in Adobe Content Viewer (one without Blue ribbon), Folios downloaded from your developer.ipa, Folios shared via Social media (There is a criteria for this) and Folios downloaded from your Live App.
"Folios shared via Social media (There is a criteria for this)" What criteria is this?
For example if you publish a Folio with 40 Articles and share some articles via social media. Adobe will track number of articles viewed by end users and 40 article views would count as 1 Folio Download.
