Hey,
when I use the package "biblatex-chicago" autocompletion for most cite commands will not function (command higlighting is turned off as well). Plus, when I type the /cite command (which still does work) the list of citation keys is empty.
I switched from
\usepackage[style=authoryear-comp,maxbibnames=10,maxcitenames=2]
where everything was fine to
usepackage[authordate,backend=biber].
Version 3.1.2
Operating system Windows 10
development has moved to https://github.com/texstudio-org/texstudio
please report there
