IronDrac: I 'm not sure what is the cause but some games codes can be activated multiple times but will never appear in the game library this has happen with me a couple of times
I've never experienced this problem before, but that's only because I've taken all the Amazon Prime subscription games codes I've used so far directly from the source, not third-hand like this forum topic.
IronDrac: it even says:
"Code redeemed successfully!
Great news! You’ve successfully added 1 item to your GOG account.
⚠️ Due to high demand, your game might take a little longer to appear in your Owned Games section, but don’t worry — it’ll be there shortly!"
This is something I experience very often with codes coming from Amazon Prime subscriptions, but as I wrote above, as I take these codes directly from the source, it is on this basis that I wrote and posted my previous response.
