Issue Description: Microsoft Copilot Readiness and Microsoft 365 apps reports from July 31, 2025 onward may be unavailable.

Current Update: 08/08/2025 08:35:00 AM – Microsoft have determined that a portion of service storage had dropped below their manageable service performance thresholds, blocking the expected data flow between our services and prevented data from July 31, 2025, onwards from flowing from the data source for Copilot Readiness and Microsoft 365 apps reports. After addressing the offending data flow, their internal service telemetry has verified that impact has been remediated.

Scope of impact: Any user or admin attempting to generate Microsoft Copilot Readiness or Microsoft 365 apps reports that included data from July 31, 2025, or later may have been impacted.

Root cause: A portion of service storage dropped below our manageable service performance thresholds, blocking the expected data flow between our services and prevented data from July 31, 2025, onwards from flowing from the data source for affected reports.

Next update by: Microsoft are further analyzing the affected service storage to isolate the source for the lower than expected service performance so they can prevent similar issues in the future.
