Hey @SilentException, yes, we're aware of this.
Once every couple hours your stats are recalculated.
This may be triggered by you visiting the dashboard.
In that case it recalculated the stats while loading the page.
The more orders you have, the longer that takes.
So take it as a point of pride!
Because you've been such a long customer of Queal, our server needs to churn away for a while at calculating your stats.
