Pressing Synchronize Library makes the text “Syncing Library” appear very quickly on the bottom bar of the program, then quickly disappear. The “My Library” section on the site is empty despite being logged in on the program and site.
In addition, pressing the “installed games only” option in the client has no difference on any of the games. My example for this is Skyrim in Steam, as Lutris prints “[steam]:Setting The Elder Scrolls V: Skyrim as uninstalled” when running Import games. “Use dark theme” also has no visible difference.
