Click Save to update the subscription. The past due billing will be handled in one of the following ways:
If the card has not reached the maximum number of autocharge retries, the next autocharge attempt will run all current and past due charge.
If the maximum number of auto-charge retries has been reached, you need to manually run the past due charges. All future charges will run automatically using the new card.
