I’m using the Codex Mac app. Today, June 23, 2026, I upgraded my subscription from Plus to Pro 5x, but I still received a “model limit reached” warning while the app showed I had about 78% of my 5-hour quota remaining.

What steps can reproduce the bug?

The app warned that the model limit had been reached even though the 5-hour quota indicator still showed 78% remaining.

What is the expected behavior?

After switching to Pro 5x, the app should correctly recognize the new subscription quota and allow usage while quota remains.
