After a lot of testing I have found out that based on your Office 365 subscription, you have different application functionality and menu items within Power BI.
Because of this one of our customers cannot edit the Icon for a Power BI workspace or any other settings that are outlined in the Power BI documentation for changing workspace setting in Power BI inside of Office 365, found here: https://powerbi.microsoft.com/en-us/documentation/powerbi-service-manage-your-group-in-power-bi-and-office-365/ .
It is not fair of Microsoft to require someone to have another product license to perform basic changes to settings within Power BI when that person is a paying customer of Power BI and Office 365.
Can someone at Microsoft please tell me why there is inaccurate and unsupported documentation on the official Power BI documentation webpage. Additionally, what should I tell my client and Microsoft's customer in regards to how she should change the settings of her workspaces if she does not have an Office365 subscription that includes other specific Microsoft software applications?
For example, they have Office365 ProPlus with Power BI Pro and can not see the Members, Calendar, and Conversation links in the workspace navigation menu that is shown in screenshots on this page: https://powerbi.microsoft.com/en-us/documentation/powerbi-service-manage-your-group-in-power-bi-and-office-365/ .
