Cannot select shipping method in Apple Pay payment sheet

[pignion]

Describe the bug When using Apple Pay from the shopping cart, I cannot select a shipping method, even when Magento provides multiple shipping methods. The first shipping method provided by Magento is automatically chosen.

To Reproduce Steps to reproduce the behavior:

1. As a guest user, add an item to the cart
2. Go to the shopping cart
3. Click the Apple Pay button
4. In the payment sheet, select a shipping address that will return multiple shipping methods from Magento

Expected behavior

• I can select which shipping method I want to use.
• If I've already selected a shipping method in Magento, the one I selected should be selected in the Apple Pay payment sheet, not simply the first one.

Actual behavior

• No shipping methods are displayed, and first shipping method is chosen.
• I cannot change shipping method from the payment sheet.
• If I customer selects a shipping method in Magento, then initiate an Apple Pay session from the cart; the selected shipping method is changed to the first one returned by Magento.

Desktop (please complete the following information):

Adyen Versions

• adyen/adyen-magento2-expresscheckout: 2.1.0
• adyen/module-payment: 9.7.2

Additional context The ApplePaySession's completeShippingContactSelection should be called with all available shipping methods, which will cause them to show up as options on the payment sheet, according to the Apple Documentation

When I step through button.js and get to the point where the shipping methods are retrieved from Magento, I can see multiple shipping methods returned, but they seem to be being discarded.

I can see pretty clearly here where Adyen's Express Payment javascript is selecting the first available method rather than checking to see what shipping method has been selected in Magento:

Additional Information: I've confirmed that when I downgrade to 2.0.0, I can see shipping methods, so this appears to be a regression in 2.1.0 onward, where I can reproduce the issue.
