Seeing intermittent crashes on canMakePaymentsUsingNetworks() IPhone 6 and 6+

Hey there,

Upon creating a new build and .ipa of our application apple pay looks to be crashing sometimes on the IPhone 6 and 6+ models. It looks to be blowing up when it tried to invoke canMakePaymentsUsingNetworks on the PKPaymentAuthorizationViewController. Our code implementaiton of this has not changes and it works fine on the 7 and X, but only after a few tries on the 6 and 6+. Our analytics tool is throwing SIGSEV crashes that look something like this

Our Implemetation of the code is as follows

/*
* Checks the PassKit method for determining if the device has any cards in PassBook that will work with
* this application
*
*/
- (void) canMakePaymentsUsingNetworks:(CDVInvokedUrlCommand *)command{
    [self.commandDelegate runInBackground:^{
        CDVCommandStatus status = CDVCommandStatus_ERROR;
      
        if ([PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:[ApplePayConfig paymentNetworks]]) {
            status = CDVCommandStatus_OK;
        }
      
        [self.commandDelegate sendPluginResult:[CDVPluginResult resultWithStatus:status] callbackId:command.callbackId];
    }];
}

we are also calling canMakePayments before this method in the following way

/*
* Checks the PassKit method for determining if Apple Pay is enabled or available on this device
* As of iOS 8, the Simulator does not support ApplePay.
*
*/
- (void) canMakePayments:(CDVInvokedUrlCommand *)command{
    [self.commandDelegate runInBackground:^{
        CDVCommandStatus status = CDVCommandStatus_ERROR;
       
        if ([PKPaymentAuthorizationViewController canMakePayments]) {
            status = CDVCommandStatus_OK;
        }
       
        [self.commandDelegate sendPluginResult:[CDVPluginResult resultWithStatus:status] callbackId:command.callbackId];
    }];
}

One interesting thing is that we are able to reproduce the crashes the majority of the time with .ipa's downloaded from TestFlight or directly from the app store, but it's a lot harder with development builds or running a device tethered to xCode (we haven't been able to reproduce it this way). If anyone has any insights at all it would be greatly appreciated!
