I used it with the latest Chrome Browser (as recommended) and Windows 10 (as recommended) and the web interface WOULD NOT (display, download or) print my postage label.

Suggestion 1 - make the application work properly. It managed to create and download my proof of postage form ok, so no reason it could not have similarly produced my postage label.

Suggestion 2 - provide freephone help! To add insult to injury, I then had to pay a shedload of premium rate call costs while a (very nice) lady helped me to get a label (by using the UNrecommended browser!). A huge waste of my time and money, when the previous Print Online Postage service always worked perfectly.

When you send an item to a certain country only the relevant services should be appear and be available.
so for example we ship a parcel to czech republic, the only way you can ship to this country is tracked & signed, but all options are available, (signed or tracked)
If the service is not available for that country their should not be an option.
We have many items returned for this reason, but no refund , so you have to do a new label and pay twice.
This has been an issue since the launch of Click and drop but is still not resolved. I raise every time with account manager and I am told it is high priority but is clearly not.

ebay integration for non-EU countries does not allow you to input HS Tariffs or change the price of product on the C&D shipping page now, you have to go to product and back again, if it is going to be the customs rule now that these have to be done digitally then we need the chance to adjust the price of product and check HS code is right before committing to shipping, I refund TAX on ebay purchases made from outside the EU but as the ebay/C&D import as already took place then the product price is showing wrong to what I right on my CN22 for the shipment label

How on earth do you import (via dropbox) a order with more than 1 item?
I've avoided using items until now, but obviously I need to add electronic customs information now for some overseas countries.
I can see how you can give details on 1 item (and the example .xls shows this), but how on earth do you give multiple items within 1 package, each with a different country of origin and customs code???

I cannot find any documentation for this. At least with DMO, all information for on demand was in 1 document, so you knew where to look!
Giving another example upload file, with multiple items in 1 package, showing customs information would help

Why is it that you have done all the work for populating the CN23 for the pre electronic information yet you have not bothered to have it populate all the required fields such as the sender and the recipient ? It seem obvious to have these populated as the information is there. Alos the category is a required field so why can we not populate that from any import?
The current version of the CN23 means that every one has to have handwritten information added making them look untidy and time consuming to fill in our details and the customer details when this information is already available. We send a large number parcels that require this form and I had hoped that with the new requirements for pre electronic information that Royal Mail would have added this to the form to help speed up customers processes.
Why was this not done?

I tried using the service without creating account using the option for 'one-off or a handful of items'. In the pages I'd navigated to get there it had indicated I could use this for a few items at once. It took me through each item one at a time and I assumed I could go back and find all of them to group the labels on a page. It didn't - it seems the confirmation page was the only place I had the one-off chance to access each label. Now I have no way to access 2 out of 3 orders I've paid for! Why can't you a) make it clear you can only process one order at a time, and b) include a link in the confirmation email to the label PDF.

Can you please advise us when the automatic submission of customs data to other countries goes live. I note that as you are still unable to edit/change products once added to an order, or unable to split an order, much of the product data that is attached to my international labels is incorrect. I just override the weight to be the correct value and leave the incorrect product information as is and hand write a CN22 form. So, given the product information, when submitted electronically by RM on behalf of the sender is a legal declaration of the contents of a parcel, we really do either need a way of editing an orders contents, or disabling the submission of incorrect product data for an order.

I guess an alternative is to get a black marker and cross out the customs barcode on the label so it cannot be scanned.
