Short answer: Payments can fail because of card declines, expired cards, insufficient funds, authentication challenges, or billing checks.
Steps
Open Account and check the subscription status.
Select Manage billing.
Update your payment method or complete any required card authentication in Stripe.
Return to Typeshutter after the payment succeeds.
Refresh your account page to confirm your subscription status.
Notes
When payment is past due, Typeshutter may pause future credit refreshes until payment succeeds.
Stripe may ask for 3D Secure authentication depending on your bank.
Troubleshooting
If multiple cards fail, contact your bank or card issuer.
If Stripe shows payment succeeded but Typeshutter still says past due, contact support with the invoice date.
