Including Entry Property in Object I'm trying to get the category title to render within the following object but it's just returning it as the static string instead of the {{ category.title }} actually rendering.

{% set seo = craft.seo.custom(
    'Welcome back, {{ category.title }}',
    'Test Meta Description!'
) %}
You want something like this:

{% set seo = craft.seo.custom(
    'Welcome back, ' ~ category.title ~ ', Test Meta Description!'
) %}


Or even more clear (to me anyway):

{% set seo = craft.seo.custom(
    "Welcome back, #{category.title}, Test Meta Description!"
) %}
