When you make deliveries to multiple destination locations controlled by MobileDOCK, and you have added each of the credentials for these locations (see here how to add credentials), you need to identify which of the locations you want to book into when making an appointment.
When you click on the New Appointment button
You will be presented with a popup panel with the logo/icon for each of the destination location companies you have registered
You must tap on the logo/icon which matches the destination location company.
You can be sure you have selected the correct destination location company, as the booking page will show the logo/icon in the top. Here we tapped on Westfield.
If you have selected the wrong destination location company, you can simply tap the New Appointment button again, and select from the list again.
If you proceed with a booking at the wrong destination location, you will NOT have an appointment at your intended destination, and will likely be denied entry.
