User’s custom CSS keeps disappearing. Override styles issue.

At least the header styles, which are configured in the header builder, are constantly being applied and not applied. This most likely applies to the custom CSS in the header, but it likely applies to other parts of the site as well. The problem lies in the style override queue. My custom styles don’t require !important btw.

There are no additional styles defined anywhere else in the settings. And everything works as expected on other sites with your theme.

Also, Convert large CSS files to inline styles in the performance settings does not affect the style loading order.
