I want to report that the “Popular Apps” section on the Flathub website appears to be frozen, and has not changed in several months. I’m not sure if it is supposed to update automatically, like the “new and updated apps” section, or if it is supposed to be updated manually like the editor’s choice. But it is not updating at all. It even still lists TLauncher as the 41st most popular app, despite that app being removed from Flathub.
As long as the section isn’t updating, it is somewhat misleading to call it “popular apps,” since apps change in popularity over time. I hope someone can improve it, though I understand it may not be high priority.
