Linking of Accounts

[Ripndip]

So i just preordered the game through steam and from what i understand to get the ingame rewards i needed to link my wbgames account to my pottermore /harry potter fan club account and also link my steam account to the wbgames account to get the rewards on launch day?

When you first launch the game, there will be a pop up asking you to log in to your WB account.

I asked the support and they told me you have to link your Steam account with your WB account in order to get the rewards
