Why was the credit card I used rejected?

If you used a credit card to pay for your plan that is set to expire within 30 days of a scheduled payment, then the payment attempt will be automatically rejected by our system. It will re-attempt to process your payment for a few more days. However, unless an alternative payment method is added, your credit card will keep getting rejected. In such instances, you’ll either be blocked or downgraded to the free plan (assuming you do not have any extra credits).

The system will only accept credit cards that have an expiration date at least 60 days away.
