GOG galaxy showing refunded games and demos still...
As well late to show activity in achievements in feed when quitting the game.
I have the 'demo games' showing up too. I consider that to be an issue with how the other platform deals with them, so technically it would not be a GOG Galaxy bug. So, so far I've been just 'hiding' them. But if GOG can do anything about it (preventing demo games from showing up to begin with), that would be greatly appreciated.
