I'm facing an issue with in_app_purchase 0.3.1+2 flutter plugin and iOS 13.4

The purchase dialog opens once and, if canceled, it won't open anymore.

It works fine on Android and any prior version of iOS 13.4

It happens for both, consumable and non-consumable purchases.

By investigating further, I noticed that specifically, nothing happens when calling the following FIAPaymentQueueHandler.m method:

- (void)addPayment:(SKPayment *)payment { [self.queue addPayment:payment]; }
