How can I force flathub to update its cache of the screenshots of a certain app

1

I am trying to pass all quality checks for this app: Install Coulomb on Linux | Flathub

It fails on two points:

  1. include window rounded corners and shadows.
  2. use default settings.

I fixed the first one by taking screenshots on gnome, and the app does use its default settings so I guess these two issues are connected.

Anyway I updated the screenshots on my GitHub repository, with the same names, that meant I didn’t have to modify the app stream metadata, or flatpak manifest, so no other build was triggered, and Flathub still uses the old screenshots, so how do I trigger the update, or does it get updated periodically?

Thanks in advance.

Force a change the the metainfo file, like change the filename in the screenshot link or something else. This will force it to update on the website.
