Hey I know this maybe a gog galaxy question but the achievements are unlocking in game but I'm not getting a notification that it's actually unlocked. Also I went into the in-game features of the settings and turned everything on but I'm still not getting the notification in game.

I'm experiencing the same issue. GOG Galaxy achievements have been all out of wack for a very long time. At least they're unlocking correctly, I've played other games through GOG Galaxy that showed notifications but didn't unlock the actual achievements properly.

I've gone to support for answers, but all I've gotten back were non solutions to problems I never had before.
