On Friday, May 20th, from 0900 and 1000 CDT (1400 to 1500 UTC), the Cloud Operations team will be applying updates to the APAC - Enterprise One Australia Datacenter (AWS) Power BI Report Server farm. During this time all reporting will be unavailable for customers v15+.
This is just a change to the authentication code and not a change to the version of PowerBI running on the farm.
If you do experience any issues with existing Power BI content please submit a case via https://support.planview.com.
Thank You,
Cloud Operations
