When accessing the service in Chrome, the icon for sharing a report is hidden. I am an admin on all workspaces. We have PBI Premium, that is not the issue. In Firefox and MS Edge, the icon is present.
Chrome is my company's default browser.
Chrome Version: Version 87.0.4280.66 (Official Build) (64-bit)
Firefox Version: 83.0 (64-bit)
Edge Version: 44.17763.831.0
That seems to work fine for me. Clear cache and try again later.
