glossaries package FAQ

\Gls doesn’t work with the smaller option (everything is converted to uppercase) 🔗

Redefine \acronymfont to use \textsmaller instead of \smaller:

\renewcommand{\acronymfont}[1]{\textsmaller{#1}}

This has been fixed in version 1.19.

Note that if your acronym starts with a capital letter, \Gls will produce the same text as \gls.
