What's Wrong?

My Claude Max 20x subscription, paid in full via a Gift Card (100% discount, €180.00),
has disappeared from my account entirely. The subscription is no longer visible in
Settings → Account or Settings → Billing. Claude Code is blocked and requires a Pro/Max plan.

Account details:

• Plan: Claude Max 20x
• Billing period: April 6 – May 6, 2026
• Invoice number: ZOGPXVXI-0006
• Payment method: Claude Max 20x Gift Card (100% discount applied, €180.00)
• Invoice status: Paid

What Should Happen?

The account should display Claude Max 20x as the active plan and Claude Code should
have full access until May 6, 2026.

Steps to Reproduce

1. Redeem a Claude Max 20x Gift Card on claude.ai
2. Invoice in Settings → Billing confirms payment (Invoice #ZOGPXVXI-0006, status: Paid)
3. Subscription is active for period April 6 – May 6, 2026
4. Log out and log back in
5. Settings → Account shows no active subscription
6. Claude Code blocks access, prompts to upgrade

Additional Information

• Logged out and back in multiple times — no change
• Checked on both claude.ai web interface and Claude Code — both show no active plan
• Subscription worked correctly from April 6 to April 9, 2026 (inclusive)
• On April 10, 2026 access suddenly stopped working with no changes made on my end
• Did NOT cancel the subscription
• No cancellation email received
• Invoice proof available upon request
• Support chatbot (Fin AI Agent) confirmed it cannot access billing systems to resolve

• #43257 — Max 5x showing as Free despite active billing (Apr 3, 2026)
• #41499 — Gift card Stripe proration bug destroying subscription credit

This appears to be a known backend synchronization issue between Stripe billing
and account plan status, specifically triggered by gift card redemptions using
100% off coupons.
