Save PBIX from Power BI Service Under Delivers - This blog post was going to be about how excited I was to hear that there is now an option to download a PBIX file from the Power BI Service to your PC.  Unfortunately all that glitters is not gold.  This new option in the Power BI Service promises a lot but delivers little – […]
