Watchdog app terminations related to GADVideoPlayer.
Michal @ Slumber
We've been seeing this in the crash reports for quite a long time. Currently we use Goole-Mobile-Ads 9.5.0, but it was happening on previous versions too. Currently this is the most common reason of the app being terminated. Unfortunately, I haven't been able to reproduce it.

Hi Michal,
Thank you for providing additional information. However, it would be best if you could provide a project file, so we could have full visibility in your implementation as well. This is a big help to us to further check this crashes. Rest assured that the shared project file will not be shared externally and will be used for investigation purposes only. If you can't still provide a project file due to company policy, you may modify our Sample App iOS aligning to your implementation. You can send it via Reply privately or by following the steps below.

In addition to that, I've checked your logs and the Exception Type: EXC_CRASH (SIGKILL) means that the operating system terminated the process. Then for the Termination Reason, I've seen that it has code error "0x8BADF00D" which means the operating system’s watchdog terminated the app. With that, you can check this on how you can identify the signature of an unresponsive app terminated by the watchdog, and address the issue.
