SEPA bank transfer no bank details

Hi together!

We use German Market for our website and also Mollie for the payments. The problem is, that the generated PDF has no information about the bank details, if it was send as a mail attachment. This is important, because you need the right reference code to match the payment from our client.

But if we manually download the generated PDF from the WooCommerce order overview, all bank details are available.

The German Market support told us, that it seems like, you fire the hook to insert the bank details to late. We use for this the mail “order on-hold” in WooCommerce. If we use the default WooCommerce bank transfer, there are all details inserted into this mail. But if we use it with Mollie, there are no details.

They told us, if the bank details are inserted to this mail, it will be also inserted into the attached PDF invoice. What we can do, to realize this?

Thanks in advance for the help ??
