# Mhchem broken on mobile

That's how it looks right now. I don't recall this being a problem earlier. It's like this on other questions as well.

Was it broken by some update? I haven't been around much so haven't been following what's been going on.

Thanks.

• The mhchem extension of MathJax on Chemistry.SE has been updated (apparently yesterday to version 3.0.1 and just now to version 3.0.2), which also causes a changed appearance of several posts. – Faded Giant Aug 10 '16 at 22:36
• Yes, the mhchem extension has been updated. But the red \ce indicates that it wasn't loaded at all. – mhchem Aug 11 '16 at 4:47
• Could you add the mathjax tag to the question? – mhchem Aug 11 '16 at 4:50
• Confirmed with Android app, installed today. – mhchem Aug 11 '16 at 7:39

This bug was caused by /sites route in the stackexchange api not returning MHChemMathJax in markdown_extensions due to configuration changes for the mhchem 3.0 upgrade. The fix is already rolled out, so the apps should be rendering mhchem after a restart.
