I am implementing Apple Pay in our iOS Native app.
I create PKPaymentRequest object, and display the Apple Pay payment sheet successfully. After I authorize it by Touch ID, I can get the payment token.
After I send this token to payment provider, it will shows [processing] on payment sheet. All things work well.
But when the server-side spend longer than 30 seconds, it will show error dialogue on payment sheet.

My question is that is there a timeout time for Token payment process? If Yes, is it 30 seconds?
