Hi @ilyon, thank you for reporting the crash. How often is this occurring for you? Were you able to reproduce it consistently?

Hi @ilyon, thank you for reporting the crash. How often is this occurring for you? Were you able to reproduce it consistently?

The number of occurrences is little, there are only a few times at present, and I cannot reproduce the problem.

Thanks for your response. We have narrowed down the cause and will push out a fix in the next release (iOS SDK v6.12.6) - please follow the releases in this repository to be notified of it. Thank you.
