To simplify this issue, I just have 2 hooks:
1. customtheme_preprocess_paragraph__registration_button() 2. customtheme_preprocess_paragraph__registration_button__default()
When I access a node with a registration button with a default view mode, only the first hook is called.
Also, when I access the
$variables['view_mode'] in that hook, it gives the value 'default'.
Furthermore, it only takes the paragraph--registration-button.html.twig as template, but not paragraph--registration-button--default.html.twig
I am using Drupal Core 9.5.4 and Paragraphs 1.15.0. Could this be something in my setup?
