Payment method screen not shown, but going directly to one specific option

[MetaDevelopment]

Description

Our payment form has no specific Mollie-fields and the gateway id field points to the Mollie gateway set up in Craft Commerce.

When submitting the payment form, we immediately get one specific option on the Mollie platform, credit card. Apple Pay enabled devices also show that option, but that seems to be integrated in the credit card option, so it's really just that option.
The "Payment methods" link on the Mollie platform goes to the webshop's payment page.

We've enabled several options in Mollie, so we expect to see the payment method list first, to be able to choose a method.

We've reached out to Mollie, but they say everything is configured correctly on their side and advise us to contact Craft Commerce support.

When I use gateway.fetchPaymentMethods(), I also don't see all the options - only credit card and some specific banks. When using that field to select a specific payment method (one of the banks), it doesn't make a difference.

Steps to reproduce

1. Install Craft Commerce with the Mollie gateway plugin and use a valid live Mollie API-code which has multiple payment methods enabled
2. Use the Mollie gateway (without additional parameters)
3. Submit the payment form to go to the Mollie platform

CLOSED, issue not with Commerce-Mollie: I've pushed Mollie a bit more since it's likely this is at their side. Just today they asked whether something has changed and asked to test again. It seems to be working correctly now, even though we didn't change anything and Mollie says they haven't either...
