Hi everyone, I would like to buy the new Ion Fury addition, but GOG tells me I have to own Ion Fury to be able to buy it.
Now, I do own Ion Fury, but I was gifted it from another person who bought it through GOG.
I tried importing it into GOG, and the game is running and is being recognized, but I am still not able to buy.

Is there a way to solve this?

Have you tried buying it using a web browser and not GOG Galaxy?

Yes, I tried both. Unfortunately both show me the same issue.
