Hey, typing in the community sect for the first time!

I'd like to see if anyone's able to help me with this problem

I have linked my Steam account and everything works as it should, except for the fact that the achievements for whatever reason don't sync from Steam to GOG Galaxy.

Can anyone help me with this issue?

Any help would be greatly appreciated!

I would assume, the Steam version talks through the Steam API, and not Galaxy.

And i would assume the GoG version talks to the Gog Galaxy through the API, and not steam.

Transferring them... you just have to earn them again i'd assume. Or load a game that is compatible between both versions and hope it syncs.
