In order to redeem points you'll need to start the checkout process through our normal checkout, not an accelerated checkout (Paypal, Shop Pay, Apple Pay). When logged in to your account, you'll see a 'Choose Reward' dropdown next to the coupon code box in the checkout. Apply the relevant value of point redemption and then you can continue checking out or navigate to an accelerated checkout (like Paypal, Shop Pay, Apple Pay).
At times, the system still won't recognize you are logged in - we recommend logging out and back in.
