My account it's already linked with my Steam account and i've updated it several times, then in the window where it says that Sega requests permission to access the following: Register and activate product keys in your account. I click on allow but it doesn't work, it just loads without redeeming any of the two rewards.I activated the base game a while ago and these are the rewards of Humankind that i can't redeem:

HUMANKIND - Amplified 22 Rewards

HUMANKIND - Great Zimbabwe Wonder

Please i need your help.
