Missing iOS 7 App Usage data in iTunes App Analyti

问题:

I have an app that is used by users running iOS versions from 6 to 9. But i can see app metrics only for (operating system) platform versions 8 and 9. There is no data about iOS 7 or earlier.

I checked the iTunes Connect App Analytics Guide (pdf) & App Analytics Guide (html).

It says "devices using iOS 7 or earlier are not included in App Analytics, but they are included in Sales and Trends".

"App Analytics only displays data from devices using iOS 8 or later".

I would like to know why it is so? What can i do to find out usage counts of users with previous versions of iOS?

I think Google Analytics or something similar can be used, with OS version as a custom parameter to track.

i think this might help. https://developers.google.com/analytics/devguides/collection/ios/v2/customdimsmets#overview
