Aktually, if no metadata is available, GNOME Software will display a
"Preparing software catalog..." panel while running an apt update in
the background to obtain fresh data.
Apparently, that is not working for everyone, and I haven't
investigated yet why.
My guess is though that people do get data from the Snappy store,
Flatpak or the GNOME Shell extensions catalog, which makes GNOME
Software skip the loading screen and jump right to the catalog filled
with less applications. If that is the case, I don't know yet how to
fix this issue without annoying sideeffects, the potentially easiest
thing to do would be to run an apt update once when GNOME SOftware is
first started and it finds no AppStream component with the OS vendor
as origin_kind.
