Really disappointed with Paymill. I Have been live for a couple of months now, but my customers kept using Paypal instead. Now, customers are starting to use Paymill and payments have been rejected. So I am only now informed that I checked 3D secure on my application and Shopify doesn't use 3D secure. This is really frustrating and annoying because this is resulting in lost sales only after the fact.
They should have informed all shopify customers early on that 3D secure does not work with Shopify.
