Unable to see shared workspace in Azure ML studio

We are collaborating with multiple people on Azure project. We are sharing one ResourceGroup under MSDN Subscription. I have been assigned the role Owner under that subscription. I see all the Azure resources. But when I go to the ML studio workspace, where my role is also Owner, which I can see in portal.azure.com, I don't see the workspace in the appropriate Region in the studio.azureml.net. Any suggestions why this might be the case? Any ideas will be appreciated.
