Codex credits are draining while idle / not actively used

Same here, I took a break for a day and a half, and it was already 99% when I came back just now. I came to this forum to see if this is a known issue, and I check my quota again, it is now 96%, I only loaded the app, no prompting or any work done. I am also pretty sure my weekly usage was around 62~68% as I keep strict control of my limits. But I don’t have a recording of it, so I can’t tell. But idle draining is pretty real. Really frustrating.
