Issue Description: Users may be unable summarize report content using Copilot for Microsoft Fabric

Final Update: 20/03/2026 08:45:00 AM – Microsoft reverted the offending service feature and have since validated that this successfully remediated all impact as expected through analyzing service health telemetry.

Scope of impact: Users attempting to summarize report content using Copilot for Microsoft Fabric may have been affected.

Root cause: A recent service feature introduced an unsupported value for Copilot for Microsoft Fabric API requests within the Microsoft Fabric, and resulted in impact.

Next Steps: Microsoft are reviewing their service feature review process to better understand how they might detect and prevent similar issues from occurring in the future.
