Can't add Mathjax

[philljolly]

I can't figure out how to add equations to my Anki cards with this ace extension.

For example, this doesn't work:

## Front1
<p><anki-mathjax block="true">\frac{1}{5}</anki-mathjax><br></p>

Apologies if this is not broken but I am missing the obvious.

I found that this works:

\\(\\sqrt{x}\\)

but not this:

\(\sqrt{x}\)
