If a renewal payment fails, your Profile page's Billing section will show "Payment failed, update your card" next to your plan.
What to do
- Click Manage billing to open Stripe's Customer Portal.
- Update your payment method there, a new card, or fixing whatever caused the original decline (expired card, insufficient funds, a bank fraud block, and similar).
How much time you actually have
Stripe automatically retries a failed charge a few times over the following days before a subscription is cancelled for non-payment, so there's usually no immediate rush the moment you notice it. Still, the sooner it's fixed, the safer, to avoid any interruption once retries are exhausted.
