I’ve tried various solutions from Simple CSS, to HFCM and page-specific additional CSS- nothing works.
If I try to style a specific page, that is selected as a posts page (settings/reading), NONE of the CSS changes will be applied to the page.
When I replace that specific page with another (dummy page) on the settings/reading as a post page, the styling changes are immediately live and visible.
I believe that I had a similar issue with the ‘shop’ page in the past (on another website).
As I don’t like my solution of replacing the page with a ‘dummy’ page, I’d like to get to the bottom of this.
Edit: It has nothing to do with code overrides (!important), the CSS changes are not visible at all in a dev console.
