The workspace I entered is completely empty. What happened?
If you come across a workspace that has absolutely no entries and no members, it might be that you have unintentionally opened up a new project workspace, rather than entering the actual workspace you were looking for.
In this case, please delete the unintentionally created workspace, so that the system only contains workspaces that are actually being used. See also: How can I delete a project workspace?
Now search for the workspace in which you want to participate via the workspace search function on the AGORA homepage. See also: How can I find and enter a current project workspace?
