ItunesConnect's app analytics page has two sections: Sales and Usage. For the first part, they have Autoingestion Tool. I found nothing for Usage, and I searched a lot.
The closest one was this question: heavy iTunes Connect scraping, by philipp, almost a year ago. And this one, also, about a year ago.
Does anyone know if there is a tool like the Autoingestion for Usage (Installations, Sessions, Active Devices, Crashes, etc.)?
