Export to PowerPoint (Preview) feedback

This is a great new feature. Unfortunately it did not work for the latest reports I created. There are no error messages, but only the Title Slide is created, followed by an empty slide. It only works with an older report I did created for some reason. Can it be because I have created the new reports from the Power BI Desktop version and then published them?

For me it is a limitation that this can only be done from a report view, which I own and can access. Would be great if other can also eport to PPT from a Dashboard. Even better if it would be possibile to define in the share/access rights if a specific user is yes/no able to export the dashboard to PPT. This would be good as others than the person that actually created the Dashboard would need the graphs for reporting.

If you have any suggestions why my report content turns up empty in PPT, that would be much appriciated.
