Hello,
Galaxy won't import game folder, says there's no gog games here. And by games I mean only divinity original sin II since all the other did import.
Note that it doesn't prevent me to play but then, there will be no sync for the achievments.
I required an importation since my SSD disconnected during the cleaning of my computer. I don't have net speed to play with downloads and reinstalls.

Minor issue overall.
Best regards.
