External script not displaying in posts, but works fine on pages

Hi team,

We’re trying to add a custom HTML code from an advertiser into some posts, using the ‘custom HTML’ block in the WordPress editor, but it’s not displaying at all. Example post below (ad should be just under main feature image and title, but it’s just a big white space).

However, when we try to do the same thing in a page using tagDiv Composer, it displays correctly (example below, where there’s a full-page widget displaying without any problem):

We can’t understand why the widget works fine for a page and not for a post. We’ve tried it using different themes and don’t run into the same problem, so not sure if it’s a conflict somewhere between Newspaper and the Gutenberg/Wordpress editor system.

Do you have any suggestions?

Many thanks,

stuart
