[BUG] Claude Max 20x subscription not recognized — account shows Free plan

What's Wrong?

My Claude Max 20x subscription is confirmed active in billing system, but claude.ai displays Free plan. Claude Code requires Pro/Max and does not recognize the active subscription.

Account: mkrol@sleeplab.pl
Invoice: VP1F1KRF-0009 | Receipt: 2725-0841-6027
Period: April 22 – May 22, 2026 | Amount: €162.52 (paid from balance)

This matches the pattern in issues #31012, #43257, #45890, #48399, #49744.

What Should Happen?

Account should display Claude Max 20x as active plan with full Claude Code access.

Update after re-authentication attempt (April 29, 2026):

Ran /login inside Claude Code terminal. Selected option 1 (Claude account with subscription). Browser opened the OAuth authorization page and displayed:

"Claude Max or Pro is required to connect to Claude Code" Sign up for a Max or Pro subscription to connect your account, or use your API key.

This confirms the bug is not a local auth token issue — it is a backend entitlement failure. The system does not recognize the active Max 20x subscription during the OAuth flow itself.

Summary of evidence:

• Claude Code terminal splash screen shows: Opus 4.7 (1M context) · Claude Max · mkrol@sleeplab.pl's Organization — plan IS recognized at startup
• Immediately after: Your account does not have access to Claude Code. Please run /login.
• Re-login OAuth page explicitly blocks access with "Claude Max or Pro is required"
• Settings → Billing on claude.ai: shows Free plan, no Resubscribe button
• Invoice VP1F1KRF-0009 confirms Max 20x active Apr 22 – May 22, 2026, €162.52 paid

The subscription is visible in the billing backend but the entitlement/access control layer is not activating Claude Code permissions. Re-authentication does not resolve the issue.
