Either I don't recognize where to add the translation or it's simply not possible to translate the "Additional Details" in a Custom Payment option. I tried it with langify and adding liquid code.
If it is not possible to add the translation, then this is meant to be a feature request to add the possibility. Although it seems quite strange, as it's possible to translate the name of the custom payment method.
With kind regards,
I have the same problem.
How can I translate the additional details of a particular payment option?Can't find it anywhere.
I have the Debut Theme.
Can anybody help?
