Hi,
In our application we are facing lot of watchdog crashes after iOS 15 rollout. We are not able to identify the root cause for most of these crashes which are happening from applicationWillTerminate. Can someone please check the attached crash reports and lets us know how to identify the root cause for these crashes and then how to fix them?
