Change app workspace icon without needing Office 365
You should be able to change a published app's icon picture without having Office 365, especially when paying for a power bi pro license
How is this "flagged as inappropriate"? I Believe it is a valid suggestion, because we develop reports from the desktop version of power bi, we do not need O365. But we do want pretty icons that actually fit the rest of the theme.

You create these amazing reports, themed perfectly with corporate colors and graphics, then publish them as an app to the entire company only to be left with a sad default icon you can't change. A little frustrating.
