acro package: \ac command does always print long form

[vincenthoecker]

When I'm using \ac command all over my text. But when compiling it's always the long-form. Also, the first appearance isn't long-short, it's also just long. When using [version=2] then everything works good in that way but there are other mistakes everywhere and it's not possible to load the list of acronyms.

I'm using Overleaf. My current setup is: \acsetup{list / display = all , list / sort , list / heading = none , list / template = supertabular }

Is there anyone who can help me?

Edit: I could use \acl and \acs instead, but I want to use \ac.

Did you compile at least (!) twice? acro warns you in the log if it needs to be recompiled.

If that doesn't help please provide a minimal example with which I can reproduce the problem.

[vincenthoecker]

Yeah, I tried to compile a lot of times.

But I think I found a solution for this strange problem. When I'm declaring the acronyms BEFORE \begin{document} than everything works out. However this is quite strange because using \acl and \acs worked nevertheless.

So my solution is now using a seperate acronyms.tex file with declared acronyms and then including it via \input:

\usepackage{acro}
\input{ressources/acronyms}

\begin{document}

[cgnieder]

Yes. Acronyms need to be declared in the preamble. I need to look to be sure but I believe this is documented.

This requirement is from the very beginning. That it works in the document body with version 2 is just by chance, not by design.

I need to look to be sure but I believe this is documented.

Indeed:

\section{\acro\ for the impatient}\label{sec:acro-impatient}

Acronyms are defined in the preamble
