Test Flight sessions are empty

Question

I upload builds to testflightapp.com for testers. Some of my sessions don't have logs inside, only start time and no finish time. Either there are no crash logs, so as I suppose crashes are not relative to this issue. I don't have problems with the most part of sessions, only with some. Why this could happen ?

Answer 1

For more accurate logs of their builds, you must implement the testing framework that you can find the link:
