Would you be good enough to check whether MathJax support is still functioning? I have checked Collection Settings in an existing Collection and quit and opened Notenik several times and MathJax is enabled. The code below does not display correctly in my Collection.
I don’t use Mathiax myself, so it’s quite possible that I might have inadvertently broken something and not noticed.
However I am not seeing a problem. See attached for a screenshot of my results with your code (once I removed the backticks around the math, which would force it to be displayed without any conversion).
I have made a new Collection with MathJax enabled and code is displayed correctly.
However in an existing Collection, presumably created in an older version of Notenik, code does not display correctly. Very strange but thanks for checking.
