https://developer.apple.com/documentation/apple_pay_on_the_web/applepaypaymentrequest/3955945-multitokencontexts According to this document, I know that I can initialize a multiTokenContexts when initializing ApplePayPaymentRequest. But I am now facing a tricky problem. If the user's order does not require multiTokenContexts, then I will not initialize this field when I first make ApplePayPaymentRequest. When the user is in the payment process, I may update multiTokenContexts. But this time, the update is not allowed, ApplePay will be cancelled and the payment will be closed. For example, if the user's address in Apple Pay is different, I need to update multiTokenContexts to support the payment of goods to multiple merchants, which will generate an update of multiTokenContexts. MultiTokenContexts can be updated in the onshippingcontactselected method. https://developer.apple.com/documentation/apple_pay_on_the_web/applepaysession/1778009-onshippingcontactselected My question is that from the beginning, there was no multiTokenContexts to update multiTokenContexts in onshippingcontactselected, which would cause the user to close the payment and need to manually click to pay again. This user experience is not very friendly. Is there a better way for me to go from no multiTokenContexts to multiTokenContexts without interrupting the user's payment process?

multiTokenContexts is defined as follows (https://developer.apple.com/documentation/passkit/pkpaymentrequest/multitokencontexts) You can assign a value when initializing PKPaymentRequest (https://developer.apple.com/documentation/passkit/pkpaymentrequest). However, in actual usage scenarios, when the Apple Pay address changes and PKPaymentRequestShippingContactUpdate (https://developer.apple.com/documentation/passkit/pkpaymentrequestshippingcontactupdate) is triggered, how to update multiTokenContexts? The documentation and code do not provide updates for this parameter. In contrast, Apple Pay on the Web provides newMultiTokenContexts as an update when ApplePayShippingContactUpdate (https://developer.apple.com/documentation/apple_pay_on_the_web/applepayshippingcontactupdate) is triggered. Has anyone encountered this problem? Would you happen to have any solutions? Thank you.
