Not sure what’s going on with my Codex usage 😅

Yesterday (July 21) I was at around 10% usage, and it said my limit would reset on July 25. Then a few hours later, around 00:11 on July 22, I checked again and somehow my usage had jumped back to 99% available, and now it says the next reset is July 29 instead. I’m not sure whether I should be happy or confused 😂 Has this happened to anyone else? Did OpenAI change something, or is it just a weird usage tracking bug?
