How can we help?

Check your internet connection. If other sites work, our servers may be briefly down; paper trading keeps working, and sign-in retries by itself.

Open the account menu in the app (top right) and sign out and back in. Your plan is confirmed within a minute of payment.

Make sure you copied the whole secret, and that the key was created at polymarket.us/developer for your account. The app checks it with Polymarket directly.

From your account page, Manage billing opens Stripe's portal.
