Similar to Multiply-defined labels warnings with frame labels in Beamer with againframe I get multiply-defined labels warnings. But the workaround given there does not work for following situation:
\documentclass{beamer}
\begin{document}
\begin{frame}[label=example]
\frametitle{Examples}
This text is to be shown:
\pause
In the recapitulation, this text should first get hidden
\end{frame}
\againframe<1,3>{example}
\end{document}
Label `example' multiply defined
Label `example<1>' multiply defined
The goal is: to first have a sequence, and then to recapitulate the previous slide with less (or different) sequence steps (2).
Related but different is my previous question How can I repeat frames as handout with one pause for recapitulation? which is even more difficult (and still unanswered).
