SUMMARY STEPS TO REPRODUCE 1. Fresh install of KDE neon from 2018/10/04 with 5.14.0 2. Discover don't show flatpak in the preferences. 3. Plasma-discover-flatpak is installed. ADDITIONAL INFORMATION Workaround is adding a repositorie.
Same issue on 5.14.0 test builds for Kubuntu 18.10, so this seems to be a general bugs rather that distro specific. It is also a regression since the 5.13.5 release, where even if a Flatpak repo/remote was not available, the Flatbak backend would show in the Discover settings page (with options to add repo/remotes).
