I have a Premium license for Power BI but I would like to share a dashboard with a colleague who can then click on the graph on the dashboard and it open ups in the report so they can use the slicers if required. They don't need to be able to edit it. However whenever I send them the link it asks them to get a pro license. I've added them as a member in the Workspace Access and granted them access to it. We don't want to buy loads of licenses and by everything I've read if the workspace is created in premium it should allow free users to access it? Help, I've very new to Power BI.
