We have noticed a real-time shipping rates issue with v9.0.1.3 for quantity > 1. With quantity 1 in the cart, the shipping rates returned are normal. But the SAME exact shipping rate is returned for qty 2 and higher. Our products are marked as 'Ship Separately'. We have enabled DumpXML to review what is being returned. It appears that the RTShipping function is working correctly. I suspect that all shipping calculations are based on qty 1. Any ideas on an AppConfig or other setup issue that could be causing this?
