Your problem
My problem is, i cannot seem to load CSS from an external file in my MJML template via . It is not considered neither in the GrapesJS builder nor in the rendered email. I tried e.g. “” where the mail.css was placed in /css/mail.css and the MJML template file in /html/email.mjml.twig.
I tried to fix the problem by inserting into the mj-head or the mj-body section, but neither worked.
