What do approved, pending and cancelled mean?

Approved: These points can be redeemed on rewards immediately.

Pending: These points will need to be verified before you can redeem them. This typically applies to purchases and referrals. After 14 days your points will move from pending to approved.

Cancelled: These points will not be added to your account. For example, this will happen if you cancel a purchase (the points will change from pending to cancelled).
