Storage issues with Pro License

Hi PeterSim 

What you’re experiencing is due to the difference between workspace storage usage and the app publishing process in Power BI. In Pro workspaces, the storage limit is indeed 10 GB, and the system allows you to continue uploading reports even if you temporarily exceed that limit, which is why your dummy reports upload successfully. However, when you try to update or publish the workspace app, Power BI performs additional validations and packaging of all included content. This process can fail if the workspace is at or over the storage threshold, because the app requires a consistent snapshot of all assets and cannot exceed the allocated capacity. Essentially, uploads can temporarily bypass the limit, but app publishing enforces the storage cap strictly, which is why you encounter errors only at that stage. To resolve this, you either need to delete or archive content to bring the workspace under 10 GB or upgrade to a Premium or Fabric capacity workspace, which has much higher storage limits and avoids these restrictions.
