Why does not apply MathJax extensions in my note?

I used the MathJax Extended plugin and the ‘upgreek’ package from the MathJax extension packages to render upright Greek letters in my equations. However, after enabling the plugin and even creating and applying a .sty file, it’s not working properly in my notes.

When I checked in developer mode, I found that the extension was successfully loaded, but the font rendering inside Obsidian doesn’t seem to work correctly. For example, when I input \upalpha, it should display an upright Greek letter, but instead, it appears bold and shifted upwards.

Has anyone else encountered or solved this issue?

Try a newer MathJax plugin, the one you downloaded is quite old and might not work as expected if incompatible with better versions of Obsidian.

Also, check if you’ve some active CSS snippet or theme modifying your MathJax blocks.
