platform version during Testflight beta

Is there any report (or other info) available during an app Testflight beta testing that shows how many of each platform version (iOS 11, 12, etc) is being tested? Something similar to the Apps Analytics -> Active Devices -> Platform Versions graph that is available for released apps? Related question: is there any way to discover the platform type and platform version of the anonymous testers that come in via a Public Link?


thanks,
