If you go directly to view your workspace from a share link from the SDK or the portal, you will not be able to view the normal Overview page with subscription information in the extension. You will also not be able to switch into another workspace. If you need to view another workspace, the workaround is to go directly to [Azure Machine Learning studio](https://ml.azure.com) and search for the workspace name.
