Starting at approximately 8am Wednesday, Oct 3rd through 10am Thursday, October 4th, Crashlytics experienced a data loss affecting iOS, NDK, macOS and tvOS apps. This only affected iOS, NDK, macOS, and tvOS apps that had a new release or build during this time (approximately 10% of crashes). Some crashes that were reported between 8am Wednesday to 10am Thursday unfortunately were lost and cannot be recovered. Crashes reported from 10am or later are now being processed correctly.
We are determining why our alerting missed this issue and apologize for the data loss that occurred.
