iDeal in3 not working

Hello,

We have activated payment method iDeal in 3 but it is not working, when I make a test order it asks for my birthdate and does go to the mollie checkout link, but this returns a page not found, other times there will be an error displayed on the chekout page itself: er is een fout opgetreden bij het verwerken van je bestelling. Controleer of er iets is afgeschreven via je betaalmethode en bekijk je bestelgeschiedenis voordat je de bestelling opnieuw plaatst.

The first error, that shows page not found at mollie checkout URL, does show up as an order in the backend with the status waiting for payment, I see no errors in the logs for this.

The second one does show up in the logs as a 422, it seems to be miscalculating the price and throws this error, the price is 370 and not 369,99:

in3: Failed to create Mollie payment object for order 42083: [2024-07-12T09:11:42+0000] Error executing API call (422: Unprocessable Entity): The amount of the order does not match the total amount from the order lines. Expected order amount to be €369.99 but got €370.00. Documentation: https://docs.mollie.com/overview/handling-errors. Request body: {“status”:422,”title”:”Unprocessable Entity”,”detail”:”The amount of the order does not match the total amount from the order lines. Expected order amount to be €369.99 but got €370.00″,”field”:”amount”,”_links”:{“documentation”:{“href”:”https://docs.mollie.com/overview/handling-errors”,”type”:”text/html”}}}. Field: amount

So the strange thing is that these seem to be 2 different errors that is preventing the in3 payments to work.

Can you please help?
