I'm confused by the stats on the TestFlight "builds" screen. See below.
-
There are more crashes than sessions. So the definition of "session" can't quite be what I thought. Does a session have to last more than a certain amount of time to be included? Do sessions that end in a crash not count as sessions? Do multiple invocations within a short period of time count as a single session?
-
The number of sessions falls over time. I.e. once I have released a new version, the reported "Sessions" numbers for older versions slowly fall. Maybe as soon as a user has used version N+1, all their sessions for version N are removed from the stats?
-
The "invites" column is clearly the same for every version, while it should have been slowly increasing.
Is there any value in these numbers?
