Hi,
This is really useful. We're currently testing SharePoint 365 with Power BI and I'm concerned that the solution is currently a little clunky for our end users (Managers who view the reports) who are'nt particularly techy. It's also reliant - or rather, works best with - apps when viewed on mobile devices. Ideally all end users would be able to view reports within a SharePoint site without the need to launch the PBI Service. I can see that there is an add-on to embed reports, but it looks like there are additional password prompts.
Any advice or best practice would be greatly received as this is a great tool, it's just communicating the insights to an audience that is the weak link. I know its being worked on though
