I'm trying to display the postDate of Sprout Forms entries. The docs state that you can use standard Craft CMS tags. I tried:
{% for formEntry in craft.sproutForms.entries.formHandle('contact').order(asc) %}
{{ formEntry.postDate|date('d F Y') }}
{% endfor %}
And all kind of variations but the system states no method or closure with the name "postDate". All other fields output fine.
