To collect the royalties on your account, you have to request the desired amount by clicking the green button “Request outpayment” inside your user's account Royalties > Balance.
You will be able to request your royalties as soon as your balance overcomes the corresponding threshold, if not, the “Request outpayment” button won't appear. You can find the current threshold applied to your account from My Account > Pricing.
