Codex says limit reached even though usage still shows 2% remaining

What issue are you seeing?

Codex shows that I still have 2% of usage remaining, but when I try to send a new prompt it says I have already reached the maximum limit.

What steps can reproduce the bug?

1. Open Codex with usage showing 2% remaining.
2. Try to send a new prompt.
3. Codex blocks the request and says the maximum limit has already been reached.

What is the expected behavior?

If usage still shows 2% remaining, Codex should allow new prompts until the limit is actually reached.
