[BUG] Gift subscription code shows "Gift no longer available" after first activation attempt — account stuck on Free plan

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

I received a Claude gift subscription and attempted to activate it via the redemption link. The first activation attempt appeared to process, but the subscription was never applied to my account. After that, every subsequent attempt to redeem the code results in the error:

"Gift no longer available. This gift code is no longer active."

The code was purchased on June 4, 2026, so expiration is not the issue.

What Should Happen?

The gift subscription should be successfully applied to the account for the full gifted duration. The account should be upgraded from the Free plan to the gifted plan immediately after redemption.
