kotlin.UninitializedPropertyAccessException - lateinit property session has not been initialized

[NorbertCsorgoEF]

Hi there,

We are receiving a few of these via Firebase Crashlytics across device types and OS versions.
Can you help pinpoint the issue? We could not reproduce it so far.

SDK version: 0.2.7

[RobinFarmer]

Thanks for reporting this, to confirm this issue still occurs on the newest version would you mind bumping to the newest version of the SDK. If the issue still happens on the newest version we would love to see an updated stack trace.

[NorbertCsorgoEF]

Greetings @RobinFarmer!

It must be some edge case scenario, but we still had 3 cases it with the 0.2.10 version.

Attaching all three:

stacktrace2.txt
