A/B test does not honor the font settings of a global module
Different font on variation A and B even though header is a global module and the CSS is set specifically to the font I want to use. Variation B just uses a random font I can't change.
Also maybe connected, out fnt has been uploaded but is still not selectable in the rich text font list.
Agree it seems strange that the header module is changing the font as part of an A/B test - do you have a link you can share?
If you add a custom font to HubSpot in your CSS file, it won't make it available in the font dropdown in the rich text editor - the defaults don't change. The only way to specify fonts added manually is to define them in the CSS, either at the theme/template level or within the rich text editor using a CSS class.
