If, for some reason you could not charge the credit card for some time the blue bar appears and states the one should update it´s card information.

If you resolve the issue with your card then you do not know when the next attempt, if any, to try to charge your card again will happen.

Suggestion: Add a "Charge me now" - button to retry the current card as you only can do that by resubmitting all your card info once again.
