I've just had my first Canadian order since they added the GST etc charge, and for some reason, it won't download the packing slip/invoice pages so that they can be printed, I'm just getting a blank screen but the URL appears to be correct.
Have tried on both my chrome book and phone browser, but just a blank white page on both.
All the Invoices to the US and UK that I was printing at the same downloaded as normal
Yup this was mentioned either the day, or later in the week that the tax changes happened.
Turns out to have been another glitch in the matrix to add to the list of issues affected by the run up to the release of the new Seller app, as they are now downloadable.
