In the new version (21.01), the Server management tab takes you to new page with settings for Workspaces and User management. But I find no way to go back to the main page. I have to either go back in my browser or manually enter the base url.
Clicking the SS logo should take me back. Or adding a home button will also help.
Also, baseurl/administrator/takes you to a blank workspace (that doesn’t exist) with the admin page tabs on the top.
