Lightning Experience: Newly created Opportunities show "No activity for past 30 days" message on the Home Page
|Knowledge Article Number||000233219|
|Description||A newly created Opportunity will still display on Users' Home Pages as having "No Activity for Past 30 Days":
|Resolution||This is expected behavior - The "No Activity for 30 Days" feature refers specifically to Activities (Tasks and Events) created for an Opportunity.
So even if an Opportunity is newly created or edited, unless there have been Activities created/modified, it will display as "No Activity"
