When you create a new Workspace, you'll be prompted to make a choice during the initial setup:
What's the difference between these two options?
Me & others
Supports assigning tasks to other Workspace members
Supports more advanced collaboration
All Workspace members will be visible from the team pop-out
It's just me
New tasks will be automatically assigned to you
You will not be able to assign others to tasks
Great for single or personal people
Need to switch from a personal to a normal Workspace?
Navigate to your Settings page by clicking on your profile avatar. Then, flip the toggle to switch from a personal to a normal Workspace.
Note: Personal Workspace layout is only available in Workspaces with 1 member and no guests.
