You can refresh metrics on a campaign-level and opportunity level to ensure that your data is up-to-date!
To refresh metrics for all opportunities in a campaign, or on a campaign-level, press the 3 dots icon on your campaign card. Then, you will choose "Refresh Metrics."
If you are looking to refresh metrics for a single opportunity, you can do this from the Opportunity Details page. While viewing an opportunity, you can click the refresh button on the Metrics section of the page to refresh.
Whether you are refreshing metrics on a campaign-level or opportunity-level, please give the system a few minutes to update this information you.
