I ran into a problem iOS 18.4. When using Storekit1 to purchase an SKU, the user payment was successful, but StoreKit1 did return paymentCancelled to my App. I would like to know under what circumstances this problem may occur?

The situation is slightly different: when purchasing skuA, the App receives a paymentCancelled callback. About 10 seconds later another skuB is purchased, and then the App receives two successful callbacks, containing two SKUs

Can someone help me？

I had the same problem in iOS 17.2, How to solve it?
