Opening Codex app appears to start the 5-hour usage window #27786

Description

I did not use ChatGPT or Codex overnight. At 07:49 I opened the Codex app only to check usage, sent no messages, and started no task. The usage window immediately showed a reset time of 12:49, exactly 5 hours later.

Question

• Codex and ChatGPT were not used overnight.
