I have implemented PageDown in my Flask app via Flask-PageDown.
It is working fine but mathematical expressions (MathJax) of the type:
$$ .... $$
are not rendered in the previewer via such an extension.
Also, my main template contains the following:
<script type="text/javascript" src="
https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"></script>
Can anyone help me with this?
