A bit too many issues for me, other form plugins are better

A bit too many issues in the latest releases for me. I have also discovered that it is more convenient to use a more general forms plugin. So you can use your one forms plugin for contact and payment forms. It is also nice that you are not necessarily tied to Mollie, but can also easily switch payment providers. Popular form plugins such as Gravity Forms, Ninja Forms, Formidable Forms, Contact Form 7, etc. are therefore the better choice for me. Good Mollie add-ons are also available for these plugins.
