We can no longer share a dashboard with users from our own workspace. I received the message: "This dashboard contains Power BI Pro content. Only users that have Power BI Pro will have access to it"...
JasVR Per the May 3rd announcement, everyone has to be on Pro (or a variant of Pro called "Premium") to view a shared dashboard. You can either have your users sign up for a 60-day or 1 Year pro trial for a quick fix, but you'll need Pro licenses eventually...
