I have an active ChatGPT Pro subscription. My General weekly allowance is exhausted, but GPT-5.3-Codex-Spark still shows 100% of its 5-hour allowance and 75% of its weekly allowance. I explicitly selected “GPT-5.3 Codex Spark High,” but the app displays “You’re out of Codex and Work usage.” The err…

Defaulting to fallback metadata; this can degr…
