Your monthly credits will replenish at the start of every new billing period. If you can't wait until then, you can purchase additional top-up credits. These are a one-time purchase and will never expire. To get these, go to your profile (accessible via the 'Profile' button in the left sidebar on the homescreen). In the new navigation bar at the top, click 'Credits'. Here, you'll see an overview of the available packs. Simply choose one and the credits will immediately be added to your account. The cost will be automatically be charged via your set payment method.
