Multicolumn in ToC in Beamer with Metropolis theme

Question

I was trying to get a 2-column tableofcontents in Beamer. I found one solution here which uses multicol package. Normally this works fine; but when I use it with Metropolis theme, the two columns I get are not properly aligned. The first column starts little below to the second column.

Here's my working example:

\documentclass{beamer}
\usetheme[progressbar=frametitle, block=fill]{metropolis}

\usepackage{multicol}

\begin{document}
    \section{1 Section}
    \section{2 Section}
    \section{3 Section}
    \section{4 Section}
    \section{5 Section}
    \section{6 Section} 
    \section{7 Section}
    \section{8 Section}

    \begin{frame}
    \begin{multicols}{2}
        \tableofcontents
    \end{multicols}
    \end{frame}

\end{document}

and here's the screenshot (note the position of first rows):

How can I fix this alignment issue?

Answer 1

Workaround: you could simply split the columns manually:

\documentclass{beamer}
\usetheme[progressbar=frametitle, block=fill]{metropolis}

%\usepackage{multicol}

\begin{document}
    \section{1 Section}
    \section{2 Section}
    \section{3 Section}
    \section{4 Section}
    \section{5 Section}
    \section{6 Section} 
    \section{7 Section}
    \section{8 Section}

    \begin{frame}
        \begin{columns}
            \begin{column}{.45\textwidth}
                \tableofcontents[sections=1-4]
            \end{column}
            \begin{column}{.45\textwidth}
                \tableofcontents[sections=5-8]
            \end{column}
        \end{columns}
    \end{frame}

\end{document}
