claude-code - 💡(How to fix) Fix [BUG] Pro → Max upgrade fails silently — no bank notification, PaymentIntent voided before bank is contacted

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

What's Wrong? Attempting to upgrade from Claude Pro ($20/month) to Claude Max plan fails at every attempt. Unlike a normal card decline, the payment app receives zero notification — meaning the transaction request never reaches the bank at all. This confirms the issue is on Anthropic's backend, not the card or bank.

Steps to Reproduce

1. Log into claude.ai with an active Pro subscription
2. Go to Settings → Billing
3. Click Upgrade and select Max plan
4. Enter card details and submit payment
5. Payment fails — no bank notification received, no OTP/3DS prompt

Expected Behavior Payment is processed and subscription upgrades to Max.

Actual Behavior Payment fails silently. The bank app receives no transaction notification whatsoever, confirming the PaymentIntent is being voided before it even reaches the bank. This is consistent with the void_invoice / payment_intent_unexpected_state bug reported in #55982, #59027, #55266, and #55917.

What I've Ruled Out

• Card is valid and working — same card successfully charges Claude Pro every month
• Daily transaction limit is sufficient — limit has been increased and confirmed
• Bank is not blocking — zero notification means bank was never contacted
• Not a network or browser issue

Environment

• Current Plan: Claude Pro
• Attempting to upgrade to: Claude Max
• Region: Pakistan
• Payment method: Debit/Credit card

Additional Context This appears to be the same server-side bug affecting multiple users where the upgrade invoice is voided prematurely before the client-side confirmation completes. Please investigate the subscription state machine for the Pro → Max upgrade flow.
