Invited as Workspace Admin, unable to see boards

[Siyuan You]

Thanks in advance. 

I was invited to some Workspaces as Admin. However I am not able to see any boards in some Workspaces. 

I am able to go to Workspace - Members - Collaborators page, and see my name listed as Workspace members.

If I go to Guests list, click on "View boards" button of any guest, the following popup shows up.

What could be the issue? Does it mean even though I am the admin of the Workspace, I still cannot see some boards marked as Private?

Thanks again.

It looks like you are an admin of a free workspace. Only admins of Premium workspaces can see the private boards: https://trello.com/guide/permissions-controls#user-management-trello-premium
