Tracking status lags

This app just works fine. The user interface is clean and beautiful but it seems that tracking status is not updated synchronously with the carrier website (e.g. CanadaPost), even after you click the update icon. I think the back-end of the app is not working properly. The issue prevents me from subscribing the annual service. The app gives you a rough idea where the parcels are, and that’s it. Don’t expect it to be "real-time".
