Answer
When your subscription attempts to renew for the next cycle, if the renewal payment fails due to insufficient balance or other reasons on your credit card, your subscription plan will enter an Payment Failed state, but it will not be canceled immediately. If a total of 5 payment attempts fail over a period of 21 days, the subscription will eventually be canceled.
You can log in to the Foxit official website, navigate to Plans&Products> My Subscriptions>Online Subscriptions, where your subscription plan status will be displayed as Payment Failed.
In this situation, you should follow the steps outlined in this KB article to update your Foxit account with a credit card that can be successfully charged . Our system will retry processing the payment in the following days. Once the payment is successfully processed, your subscription plan will be renewed, and your subscription status will return to active.
