I’m trying to purchase the v0 Premium subscription but the payment keeps failing despite successful authentication.
Current Behavior
Desktop: Displays a “Payment failed” error message.
Mobile: Displays a “Card declined” error message.
Authentication:3D Secure (3DS) authentication completes successfully each time.
Bank Status: No errors or blocked transactions appear in the Unicredit Bank Austria app.
What’s weird is that I also tried it a few days after it failed the first time on mobile. The full flow worked including 3DS, and the UI briefly showed that I was on the Premium plan. However, after logging in again, I was back on the Free plan with 7.5/5 credits. My card wasn’t charged, but it also didn’t show a failed transaction in my bank history.
Environment & Constraints
Bank: Unicredit Bank Austria
Card: No alternative card available.

Sorry to hear you’re experiencing this payment issue — that sounds really frustrating, especially with the UI showing Premium briefly then reverting back
You’ve shared brilliant detail about what’s happening, and I can see you’ve already got ticket #947747 open.
Could you share your v0 chat link? It will look something like https://v0.app/chat/... — this will help the team investigate what’s going on with the payment processing.
Also, just to cover all bases — are you seeing any specific error codes along with those “Payment failed” or “Card declined” messages, or just those general error messages?
