Defaetist: Ok, I managed to fix the Steam issue for me.
You will need to update the steam integration components manually. To do that completely close GOG Galaxy.
Download v0.29.1 from here: https://github.com/FriendsOfGalaxy/galaxy-integration-steam/releases
Next, you need to copy those files into Galaxys plugin folder which is located as follows:
C:\Users\Your Name\AppData\Local\GOG.com\Galaxy\plugins\installed
Replace all the files inside the steam_ca folder with the downloaded ones - restart GOG Galaxy 2.0
It should automatically detect your steam games now.
