What issue are you seeing?

My weekly Codex usage went from ~45% remaining to 0% remaining in a window where I ran nothing.

Timeline (CEST, Sep 4 2026):

• ~10:00–11:00: Usage & billing showed roughly 45% left on the weekly limit
• ~12:00–13:00: same page shows 0% left, reset Sep 7 2:05 PM
• No Codex sessions, cloud tasks, or background runs between those checks. Desktop app only; no CLI, no IDE extension, no web.

Evidence that nothing consumed it on my side:

• Analytics > Usage history shows a near-zero Codex bar for Sep 4. Heavy days were Aug 31 and Sep 1.
• GPT-5.3-Codex-Spark 5-hour window still at 100% left (resets 6:31 PM), so nothing ran on that model this morning either.
• No Work / Excel / agent usage on this account in the last 7 days. [adjust if not true]

Support case 14377883 has given two AI replies asking for more details and stating limits can't be reset; nothing has been investigated. Opening here so the metering team can see it.

What I'd like: an explanation of what was attributed to my account between 10:00 and 13:00 CEST, and whether this is a metering or attribution bug. I have 2 reset credits and am holding them until this is understood.

Screenshots attached: Usage & billing (0% weekly, Spark 100%), Analytics (flat Sep 4), out-of-usage banner.

The issue provides a desktop-app usage timeline, Usage & billing and Analytics screenshots, and support case 14377883. Start by reviewing how weekly Codex usage is attributed between the reported checks and compare it with the near-zero Sep 4 history. Done means identifying the attributed usage and determining whether the discrepancy is a metering or attribution bug.
