@linjiejiao could you, please, provide more details on this crash:

iOS version, that is affected by this crash
app crash rate
did you try to reproduce this bug?

[linjiejiao]

This crash appear on iOS 10 only. Crash rate is low, we can not reproduce it on our devices.
It never appears until we update appsflyer from 6.2.6 to 6.8.1.

[asterpang]

we also have this crash, on iOS 10.
update to 6.9.0 did not fix the issue.
