Email from Power Bi Team:
"Changes to Power BI Free are coming on June 1, 2017.
This update will provide you with enhanced data capacity and refresh rates, as well as unlimited access to all data sources. Dashboard sharing will no longer be part of Power BI Free, but will still be available with Power BI Pro.
If you’re interested in an extended Power BI Pro trial that will run June 1, 2017, to May 31, 2018, simply sign in as normal on or after June 1, 2017, and get going. Contact us to learn more about Power BI Pro."
The user who shares the dashboard has to be a PRO user, but the one who was shared the dashboard can be a FREE user?
