Hello
Is calling update to update the amount resetting the selected payment method as well?
lethal nimbus
In order to update I need to pass along an IntentConfiguration, and I can't access the old intent configuration, meaning I must create a new one (IntentConfiguration is a struct, meaning value type, so I can't keep a reference to the first instance I created). And since I have to create a new one, the selected payment method isn't set of course
thick violet
Hmm we describe the flow you're building here - https://docs.stripe.com/payments/accept-a-payment-deferred?platform=ios&type=payment&integration=paymentsheet-flowcontroller#update-payment-details
You should be able to retain old configuration reference and update it 🤔 (look at the example)

What payment method type do you have selected before you call update?

It is likely forced/expected behavior. There are certain payment method types which get unselected by design. Can you try using a card payment method?
In our docs we outline it with just this sentence
https://docs.stripe.com/payments/accept-a-payment-deferred?platform=ios&type=payment&integration=paymentsheet-flowcontroller#update-payment-details:~:text=method” buttons).-,When,-the%20update%20completes
When the update completes, update your UI with the paymentOption property in case the customer’s previously selected payment method is no longer available. If the update failed, retry it.

Ok it seems to be working with cards
But the flow isn't ideal, I might have to discard the PaymentSheet.FlowController and just use the PaymentSheet

Gotcha. This is done to makes sure the correct values are shown in UI (for example, the pay button, the Apple Pay UI),
The example being, I select Apple Pay, I authorize $10 purchase but then the amount gets changed after I authorized a purchase
I'd need to authorize the payment again
this is mandated by Apple

I see, that makes sense
thick violet
and prob is not limited to just Apple Pay
