Remove an Account or Opportunity Team Using the Salesforce App
When an account or opportunity team isn’t needed, account or opportunity owners can remove the entire team with a tap. Previously, you had to remove a team one member at a time.
Where: This change applies to Lightning Experience and all versions of the Salesforce app in Enterprise, Performance, Unlimited, and Developer editions.
How: To remove a team, on the team’s related list, tap Remove All Members.
