Calculator screenshots missing
I'm not sure this is the right place to report this, or how to analyze the cause of this further. Calculator doesn't show its screenshots; the files are missing. For example https://apps.gnome.org/assets/screenshots/org.gnome.Calculator/basic-mode.png is missing. But in the appdata it looks to be correctly defined:
<screenshot type="default">
<caption>Basic Mode</caption>
<image>https://static.gnome.org/appdata/gnome-43/calculator/basic-mode.png</image>
</screenshot>
And that file https://static.gnome.org/appdata/gnome-43/calculator/basic-mode.png exists.
