Hello,
The capture is related to "Stripe Checkout" which is a different API of Stripe.
The Stripe V3 (with Connect) plugin is based on the version 3 of the StripeJS API, compatible with Payment Intent (for SCA) and Stripe Elements.
Unfortunately, Stripe Elements, which had great ambitions, did not evolved as planned.
You can see more about Stripe Checkout and Stripe Elements in that page :
stripe.com/docs/payments/accept-a-paymen...able-payment-methods
And the Theme system :
stripe.com/docs/elements/appearance-api
please note that the Payment method selector changed few months ago and is still in progress, as noted in the first link
We’re currently designing a new way to integrate the Payment Element, which allows you to create the PaymentIntent or SetupIntent after you render the Payment Element. If you’re interested in learning more about this feature, sign up for the beta.
We're waiting for a stable version of they API in order to update the plugin and not use an API which will be deprecated in a few months.
Regards,
