In App Purchase Callback not received

Test lost orders, cannot receive Apple callbacks on iOS13 and iOS14 systems, but iOS12 and below are good
steps:
  1. Monitor the transaction queue:

[SKPaymentQueue.defaultQueue addTransactionObserver:self];

Implementation protocol method:
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions

2. Initiate a sandbox payment, after the payment is successful, kill the APP before receiving the callback

3. Restart the app. At this time, the protocol method in iOS13 and iOS14-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions cannot receive the callback, but iOS12 and below systems can receive it

This situation began to appear in February, before iOS13 and iOS14 were good.

Has anyone else encountered this situation?

me too, but on my side iOS13 is good, cannot receive Apple callbacks on iOS14 only
Maybe it is a bug in Apple's sandbox environment and hope it will be fixed soon. The production environment has been verified, and there is no such problem.
