I’ve installed the MathJax plug-in to be able to write math by putting it inside of ... . It seems to work fine on the computer; it previews correctly and when posted it looks the same. However, when I tried to preview \int\_1^2 x = 1 + 1 on mobile, instead of the preview showing the correct rendering with an integral, it just returned \int\_1^2 x = 1 + 1. Is this a bug? Or just a limitation of mobile? I hope it can be fixed since it’s very useful to be able to preview complex MathJax code before posting it to the world.

Seems to be deliberate (for reasons unknown to me 😅 )
