Reestablecible no muestra el número del teorema

Question

Aprendí sobre reestablecible deesterespuesta. Sin embargo, cuando pongo el teorema en el apéndice, su referencia no tiene número. Aquí hay un MWE:

\documentclass{amsart}
\usepackage{thmtools} 
\usepackage{thm-restate}
\newtheorem{theorem}{Theorem}[section]
\usepackage{hyperref}

\begin{document}


\begin{restatable*}{theorem}{thm}
  Everybody knows that $1 + 1 = 2$.
\end{restatable*}

I would like this \ref{thm} to display A.1.

\appendix
\section{Proofs}
\thm\label{thm}
\begin{proof}
  Proof is trivial.
\end{proof}

\end{document}

Answer 1

Mueva el \label{thm}al restatable*entorno:

\documentclass{amsart}
\usepackage{thmtools} 
\usepackage{thm-restate}
\newtheorem{theorem}{Theorem}[section]
\usepackage{hyperref}

\begin{document}


\begin{restatable*}{theorem}{thm}\label{thm} % <<< \label moved to here
  Everybody knows that $1 + 1 = 2$.
\end{restatable*}

I would like this \ref{thm} to display A.1.

\appendix
\section{Proofs}
\thm
\begin{proof}
  Proof is trivial.
\end{proof}
