I'm not sure which update you'are talking about. Looks like this particular bug has been fixed as I can now install the Vivaldi browser via gnome-software, however it doesn't have a launch button after install? Not sure what's up with that.
If your talking about not being able to find non-free software, well I can find Steam(wasn't able to before) but Ubuntu restricted access is nowhere to be found. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1575429 Title: Gnome Software doesn't allow non-free software Status in gnome-software package in Ubuntu: Incomplete Bug description: Gnome Software doesn't allow non-free software to be installed, even if installing directly by the .deb file, such as Steam.
