How do i remove a group from my app and workspaces.

You can leave a group from the YourDriverApp through messages / open group / click groupname / leave group.

Or if you are the owner of the group, you can delete the fleet from the portal, https://portal.yourdriverapp.com

Login into you workspace navigate to settings / general / scroll to the bottom / delete fleet.

You can also delete an workspace from the workspace selection upon login or at the to navigation bar.
