Quite a while (... years) ago I've come across some undesirable behaviour of the beamer package when starting to use \pause inside align[*] environments. I wouldn't have seen it if a

Package nag Warning: Environment eqnarray is obsolete.

had not motivated me to replace eqnarray* with align*. Here my MWE:

        A &= B + C \\\pause
        B &= D + E \\\pause
        C &= F + G
        A &= B + C \\\pause
        B &= D + E \\\pause
        C &= F + G

With eqnarray*, \pause works perfectly, although this and that post refer to the beamer manual suggesting there to be no acceptable solution using \pause inside array-like environments. (BTW: Found it helpful to know that \pause can be used in listings.)

So, thank you for any hints on some non-amsmath but nag-compliant alternative.

    I'm not sure why you call a documented behaviour "unexpected", but you can find a workaround at topanswers.xyz/tex?q=1126 Commented Dec 3, 2023 at 23:27
  • Thanks a lot for this hint. Well, I should have written "undesired" but it has definitely been "unexpected" to me for years until I found some time to search for hints and came across the documentation. So, mea culpa, hope my question is a still valid.
