Have you got it working with the todonotes package? Seems to not show \todo{}s

Repro:

% in the header
\usepackage{todonotes}

...

% in the body
\todo{Foobar}

Observed - expected: The todo doesn't show up, unlike in normal LaTeX papers.

Note I get a warning to add \setlength {\marginparwidth }{2cm} before including todonotes, but that doesn't seem to fix it.

The poster displays when compiled on Overleaf using pdfLatex (2022). However, there appear to be undefined control sequence errors in main.tex from the compiler.

l.67 \begin{document}

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., \hobx'), type I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
