Ooh so it was the thing, it takes 24 hours to take action. I will make the changes on GOG that I forgot to. Thank you very much for your quick response! It helped me a lot. I guess it's alright now!It seems like your Origin profile is still partially private. There's a separate setting "Allow users who can see my profile to view my Achievements" that needs to be checked. If you've already checked this it can take up to 24 hours for the privacy settings change to take effect on Origin so that may be the issue as well.
GOG also appears to be private. The main profile page is visible but the games section isn't, make sure the setting "YOUR FULL GAME LIBRARY CAN BE SEEN BY" is set to all visitors.
I think those are the only issues I see. For Blizzard only certain games are tracked (WoW, SC2 and Overwatch).
