Matrix (pivotTable) visuals in PBIR-format (enhanced report format) reports stopped rendering
Issue:
Matrix (pivotTable) visuals in PBIR-format (enhanced report format) reports stopped rendering — query never returns, visual times out empty. PBIR-Legacy reports with identical visuals are unaffected.
## Symptom
Since 2026-07-27 ~08:00 UTC (verified working at 07:30 UTC, broken by ~08:15 UTC, no changes on our side in that window), every native matrix (`visualType: "pivotTable"`) in a report stored in the enhanced report format (PBIR) failed to render:

The issue: reports that are authored in June declared an older version stamp in `definition/report.json`: "reportVersionAtImport": { "visual": "2.9.0", "report": "3.3.0", "page": "2.1.0" }
Changing only this one line to the current values — `{ "visual": "2.11.0", "report": "3.4.0", "page": "2.3.1" }` — makes the same matrix render normally again. Nothing else needed to change. We verified this both ways (old value → matrix blank; new value → renders).
So it appears the service update around 2026-07-27 broke matrix rendering for PBIR reports carrying older `reportVersionAtImport` values. Any user with PBIR reports authored before the update may have silently blank matrix visuals — applying this one-line change to the reports and everything works as expected.

Does this affect Desktop as well when working with older visuals after the June update?
It was effected only on the Power BI service
Hi v-emohankira
Thank you for the clarification. Since the issue is occurring only in the Power BI Service and not in other environments, it would be best to create a Microsoft Fabric Support and Status | Microsoft Fabric for further investigation.
