Unable to save converted report” Error in Power BI Service – Looking for Solutions

Hi AmiraS ,

Sorry for the delay response and thank you for the update and for confirming the behavior.

Currently, what you are experiencing aligns with a known limitation where reports converted to the enhanced (TMDL) format in the Service can retain unsupported metadata. Unfortunately, there is currently no supported way to bulk-repair or reverse this state directly in the Power BI Service.

Regarding the support ticket and the Issues forum post: responses are not immediate and typically depend on engineering triage and prioritization. Not receiving an update yet does not indicate a problem with your submission, but rather that it is under review.

For now, the only reliable mitigation is the approach you already validated re-saving the report as a new PBIX in the latest Power BI Desktop and republishing. While this is time-consuming for multiple reports, it is the only known method that fully clears the unsupported metadata.

If you have multiple reports affected, you may want to prioritize critical ones first while awaiting an update from the product team via your support ticket or the Issues forum. Any permanent fix or tooling improvement would need to come from the service side.

We appreciate your patience and recommend monitoring the ticket for updates from engineering.
