Drupal - How to print date in format «long» on node.html.twig template?
you are not using the actual timestamp. Here's what you should do:
{% set date = node.createdtime|format_date('long') %}
See? You only need to replace created with createdtime. Hope this helps.
Try in this way.
{% set date = node.created %}
{{ set date|date("m/d/Y") }}
