The Stream tool will allow you to track the performance of posts based on specific keywords or mentions all in the same place, however sometimes you might feel like the reach and impressions might not be upto date if that's ever the case you can use the refresh feature.

When on the Stream or content Tab inside the Workflow, you will see your posts, click on the three dots on the top right hand and simply click on "Refresh Insights"

After a few seconds you will see a success message on the top right

And the post data will be updated
