We are observing a discrepancy in crash data between the App Store Connect UI and the App Analytics APIs for our iOS application. For example: On March 10, App Store Connect shows approximately 2,443 crashes (average ~2K/day). However, in our analytics database (fetched via App Analytics APIs), we are seeing 10,000+ crashes for the same date. APIs Used (IDs masked): /v1/apps/{app_id}/analyticsReportRequests /v1/analyticsReportRequests/{request_id}/reports?filter[category]=APP_USAGE /v1/analyticsReports/{report_id}/instances?filter[processingDate]=YYYY-MM-DD&filter[granularity]=DAILY /v1/analyticsReportInstances/{instance_id}/segments Clarifications Required: What could be the reason for the significant difference in crash counts between App Store Connect UI and Analytics API Are there differences in how crashes are counted in: UI metrics vs raw analytics reports? Deduplication, session-level vs event-level aggregation? Is there any known aggregation rule, or filtering applied in the UI that is not reflected in the API data? Which source should be considered the accurate/authoritative count for reporting purposes? Any clarification or guidance on this discrepancy would be greatly appreciated.
