Hi, thanks for try.
What did you require payment method?? This plugin support card payment and apple pay, google pay, only. If many others need the payment method you need, will consider implementing it. or please create pull request.
Thanks.

We need SOFORT and DEBIT payment. They are most common in Europe for B2B payments.

@PaintedShepherd

they don't show up in our paymentSheet.

https://stripe.com/docs/payments/sofort/accept-a-payment

This seems to be not paymentSheet function, and not settings by dashboard only. We need to implement new features in this plugin. I won't have time to implement it right away, but welcome to create a pull request.

Visa (debit) and Mastercard (debit): https://stripe.com/docs/testing can be able to use. Please try again.

If you said about https://stripe.com/docs/payments/bank-debits , this is new function too. And these function can't use in Japan...

Thanks.

@danielalbrecht @PaintedShepherd Did you adapt this plugin for production? If yes, please tell us what app. Please help us to develop this plugin in 2022.

Thanks.

Isn't it necessary to add configuration.allowsDelayedPaymentMethods = true (Swift Notation) aswell to allow these payment methods?

[phal0r]

Just wanted to add:
The combination SetupIntent + Sepa/Sofort does not work in PaymentSheet, because it is not yet supported by Stripe.

FWIW, Stripe does have support for 'us_bank_account' for in app browser usage. However, its a hidden opt in feature that you have to request. Its their "webview" payment feature. If you ask about it, they should be able to turn it on for you.
