[aixiaoqing]

Hi there,

It seems that after updating our application to version 6.2.5 of the plugin,then we uodate to version 6.2.6 also crashes. we've started receiving an uptick in EXC_BAD_ACCESS KERN_INVALID_ADDRESS crashes. Example crash log, as reported on Firebase, is as follows:

Hi @aixiaoqing,

Thank you for reaching out! What's the frequency of the crash? From what I understand, it was not happening before v6.2.5. Could you confirm it? Were you able to reproduce it?

[aixiaoqing]

I'm sure, it was not happening before v6.2.5. I can't reproduce it.

Hi @aixiaoqing,

We aren't able to reproduce the crash. However, we just released a new version 6.3.0. Could you try and see if the crash is still happening?

Hi @af-margot I have just experienced this bug using version 6.8.0. It's our first release with appsflyer integration. Can't compare to previous versions.

I believe it's exactly this issue which is claimed to be fixed but apparently it's not :( https://github.com/AppsFlyerSDK/AppsFlyerFramework/issues/192
