Additional context

Although the payment fails, it seems that Apple Pay prompt correct detects sandbox mode:

Apple Pay on sandbox on simulator is currently unsupported, and we recommend testing with a physical device please check updated docs in https://github.com/square/in-app-payments-react-native-plugin/blob/master/docs/enable-applepay.md
