Created attachment 185291 [details] Demonstration of failing to add applications from a flatpak. Any Flatpak application cannot add/install applications. For example, Web Apps (net.codelogistics.webapps) goes through the installation dialogue and even pops up with the Add Application.. dialogue from Plasma, but when I press Accept, nothing happens. Similar issue is also present in Steam, which is also unable to add entries to the Application Launcher, and in Web by GNOME when any PWA is attempted to be installed.
I can confirm this. 1. Install net.codelogistics.webapps and open it 2. Add new app, I tried with https://silverbullet.md 3. Popup for "Add application..." appears, the Web Apps app shows it in the background 4. Press accept 5. It's gone!
