If you need to update your credit card information for your paid subscription, just go to the profile icon in the top right corner of your LANDR account and then click on 'Account settings' and then on 'Edit Payment Methods' in the Billing section.
Click on 'EDIT SUBSCRIPTION CARD' next to your subscription card.
Update your info and save it. All of your future payments will be processed with your updated card.
If you paid using PayPal, you'll have to update your information from your PayPal account. Once you do this, we'll automatically bill all future payments to your newly updated PayPal account.
