Dear All, the new exporter does not seem to handle \begin/\end inside \( ... \). If the org file contains \(f = \begin{cases} t & 1\\ f & 2\\ \end{cases} \) the resulting tex file contains $\backslash$(f = \begin{cases} t & 1\\ f & 2\\ \end{cases} $\backslash$) Is there a known fix or workaround? Thanks and best regards, Marko
