Have you ever wondered if you could remove one of your team members from the team? You can do that in your account settings.
Go to your account settings. Click on the "Manage team" section and press on the trash bin icon on the right side next to the team member you want to remove. Once you click on it, you will need to type "Delete" to finish removing a user from the team.
Please note that once a user is removed, all of the connected sources by that user will be removed, too. Please make sure the sources are transferred by following this guide before completing this action.
