ariaspi: Unfortunately, you must use the GOG Galaxy client for the "MY REWARDS" to work. If you use the normal way (the installers), then MY REWARDS won't be available for you.
MadDocRen: Hi! I am using GOG galaxy client, I just don't know how to link it to MY REWARDS. Is it inside Cyberpunk game or is it in the client somewhere?
You will be able to claim those rewards on the launch day :)
As for the links for goodies that show up and ask to log in - unfortunately, this is a bug and we are working on it. All digital goodies will be also available to download on the launch day.
