Hi,
Using 10.14.1
When adding a percentage campaign using a Voucher, Checkout reports that it cannot find the voucher (Both using VoucherList and Voucher Order Field). This is when setting the discount to a "Product Discount".
However setting the Discount Type to "Order Discount", it works fine.
Using 10.8.1
This works flawlessly (Might work in later versions too, haven't tested). Both with Order and Product Discount.
Haven't had time to debug any deeper. - Tested on a clean solution with Swift 1.26.6
Best Regards
Kenneth Holm
