Data.com Prospecting Insights in Lightning Separated from News Component

Prospecting Insights is now a separate component in Lightning Experience. Previously, it was included in the News component. In some orgs the News component was moved in Summer ’17, but the Prospecting Insights component remains on account and opportunity pages. You can move or remove it any time using the Lightning App Builder. This change applies to Lightning Experience only.
