If you have a monthly or annual subscription and want to change to the other one (if it's available), you can do so on the billing and subscriptions tab from your account settings:
Navigate to billing and subscriptions
Click on Manage Subscription
Select your desired subscription frequency.
You'll see an alert to confirm. Click Confirm.
You will be charged the new rate at the end of your billing cycle for your account.
