One quick thing to check — make sure your date range encompasses the date on which this event was logged. For example, if the event was logged today, you should change the date range to explicitly include Today. Ranges like “Last 30 Days” or “Last 7 Days” do not include Today.
If you don’t see your reports update, you should contact support in order to get to the bottom of it more quickly.
