# Android app doesn't render LaTeX content in comments

I'm using the Stack Exchange app for Android. The app displays TeX formulas inside questions and answers as expected, but not in comments. Here it shows only the raw TeX code. I first noticed this issue in a comment on the Electrical Engineering site.

This question came from our site for apps, scripts, and development with the Stack Exchange API.

• According to this answer you need to tap the comment first and choose "Render Mathjax" – Shadow Wizard Dec 8 '14 at 21:04
• Thanks for moving the question to this site. Is there a reason why MathJax is not enabled by default? – Paebbels Dec 8 '14 at 21:23
• It was @Tim Stone, not me, as for why not enabled by default most likely because it would slow things down too much. – Shadow Wizard Dec 8 '14 at 22:02
• I tried Render Mathjax, but it does not render \$\frac{1}{16}\$. It's still tex code. – Paebbels Dec 11 '14 at 20:40
• Weird, I thought this should be the same. Leave a comment to Kasra on his reply to the dupe, and see what he has to say. (e.g. bug or by design) – Shadow Wizard Dec 11 '14 at 20:52
• @Paebbels repro'd on my end, looking into this now. – Kasra Rahjerdi Dec 11 '14 at 21:45
• This still has not been fixed. – Jerard Puckett Dec 19 '14 at 15:45
• @KasraRahjerdi Are there any updates on this issue? – Paebbels Jan 20 '15 at 1:29
• Unlike most MathJax-enabled sites, where the delimiters for online math are single dollar signs $..$, Electrical Engineering uses the dollar sign preceded by backslash: \$.. \$. It appears that the MathJax configuration shipped with the app does not take this difference into account. I don't think that one configuration file could handle both sorts of delimiters at the same time; it seems the app should load different MathJax configurations for different sites. – user259867 Mar 15 '15 at 14:07
• @KasraRahjerdi It would be a good idea to notify math.stackexchange users of the possibility to render MathJax in the comments if they are on their mobile. How? I am not sure about the best way, but maybe in a tutorial like pop up. – Matheus Rotta Nov 16 '16 at 1:15
• @MatheusRotta this is a great idea. We can detect when it's the first time they are seeing a comment with MathJax markup in it and tell them about this functionality. – Kasra Rahjerdi Nov 16 '16 at 1:44

• Note: "Render MathJax" is available on comments that have MathJax markdown even though the site doesn't support it (e.g. Meta SE). It just won't work though. $\frac{1}{16}$ – No Distraction Wizard Feb 23 '16 at 3:44
