Please note the following about workspaces:
Workspaces are entirely separated from each other. A collaborator from one workspace will not be able to access or see another workspace unless they are a member of that workspace too.
Every workspace has a separate billing. Purchasing a subscription to one workspace will not upgrade the other workspaces.
Only the workspace owners can upgrade a workspace to a paid plan, change or upgrade the subscription, and invite and remove collaborators.
Projects cannot be moved between workspaces, but they can be duplicated with one another by someone who has access to both workspaces.
How to navigate between workspaces
Head into your account.
Click on your workspaces name at the top left.
Select the workspace at the bottom of the window.
How to delete a workspace?
Make sure you don't have any projects in the workspace that you need later.
Make sure that the subscription(if there is one) is canceled. Click here for a tutorial on how to do that.
Head into your account.
