[Tex/LaTex] tcolorbox with beamer

Question

The MWE

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{tcolorbox}
\begin{document}
\begin{frame}
\begin{tcolorbox}
A\pause B
\end{tcolorbox}
\begin{tcolorbox}
A\pause B
\end{tcolorbox}
\end{frame}
\end{document}

produces three slides: A-AB, AB-A, and AB-AB, which is not what I would expect (A-, AB-A, and AB-AB).

Here somebody advises not to use \pause at all inside a tcolorbox, but the manual does mention a beamer skin, so I guess it must have support for beamer. Is there a better way to do the above?

Answer 1

Using \only instead works, though it is a bit more work.

\documentclass{beamer}
\usepackage[english]{babel}
\usepackage{tcolorbox}
\begin{document}
\begin{frame}
\begin{tcolorbox}
A\only<2->{B}
\end{tcolorbox}
\begin{tcolorbox}
\only<3->{A}\only<4>{B}
\end{tcolorbox}
\end{frame}
\end{document}
