What's Wrong?

When I redeemed the gift of 5x Max plan via url, the web interface stays in free plan. I tried re login via multiple browser with incognito mode. I can’t login Claude Code as well. My account is created via Google account.

The Fin AI agent checked and confirmed 5x Max plan is current active but setting->billing stays Free Plan as well as the whole web interface.

What Should Happen?

The web interface should switch from free plan to max plan and allow me to login Claude Code.
