Can't even remember that this ever worked - basically it's not possible to track a DHL shipment (sent via DHL in Germany) while being in Switzerland / with a Swiss IP. Once I'm traveling through Germany (German IP) everything works as expected.
Upon creation of the shipment, the initial synchronization returns "Fehler beim Laden der Daten". Afterwards won't refresh ("Status: Keiner, (Refresh) : Nie")
Thanks for looking into this, otherwise super happy with the app!
