Workspace converted from PPU to Pro during Azure outage

Like the title suggests, I had a PPU workspace that was converted to a Pro workspace during the April 2026 Azure outages.

My question: could the outage have impacted the workspace’s regional metadata, causing the system to interpret a conversion back to PPU as a cross-region move?

When I try to convert it back to PPU, I get the following error: "“Data Staging workspace cannot be reassigned because it includes Fabric items or you're attempting to move them across regions. This is not supported currently. Remove the Fabric items, or move the workspace within the same region, and then try again. Also please verify that the workspace does not contain any soft-deleted items.”

To be clear, there are no Fabric items (active or soft-deleted). I also attempted to convert the workspace to a Fabric trial capacity and received the same error, which is why I suspect a region-related issue.

For context, this workspace is somewhat isolated from the rest of the organization. Our company has since moved toward a centralized Fabric model, but these reports predate that shift and are still operating as a regional solution. They will eventually be rebuilt under the new model.

Tenant default region is East US, while this workspace (prior to conversion) was in Central US. However, attempting to assign it to Fabric capacity in either region results in the same error.

My IT team hasn’t been able to resolve this yet, so I’m trying to gather ideas before pushing to escalate to Microsoft (I don’t have direct support access). Any thoughts or similar experiences would be appreciated.
