Bug Report: LaTeX cases environment renders as raw source code on iOS ChatGPT app
`Steps to Reproduce`
  1. Open ChatGPT on the iOS app.
  2. Ask ChatGPT to display LaTeX with a system of equations using \begin{cases} ... \end{cases}.
  3. Include the cases environment inside display math, for example:

[
\boxed{
\begin{cases}
f_x=\lambda g_x\
f_y=\lambda g_y\
g(x,y)=k
\end{cases}
}
]

  1. Compare the result with the ChatGPT web version.
`Expected Result`

The LaTeX should be rendered as a properly formatted system of equations with a left brace, just like it appears on the ChatGPT web version.

`Actual Result`

On the iOS ChatGPT app, the LaTeX is displayed as raw source code instead of being rendered. The same content renders correctly on the ChatGPT web version.

`Environment`

iOS ChatGPT App / iPhone 17 Pro / iOS 26.4.2 / ChatGPT app 1.2026.104

I attached screenshots showing:

  1. The correct rendering on the ChatGPT web version.
  2. The incorrect rendering on the iOS ChatGPT app.

The issue seems to occur specifically with LaTeX that uses the cases environment, especially inside \boxed{...}.
