Hey team, sorry for the late reply!
That kind of lag makes it tough to get work done. There was an active incident in March, though I can’t confirm whether it caused the slowdown you reported. This may be resolved by now. Are you still seeing it on the latest Codex app version?
If so, please email support@openai.com with a short screen recording, your OS version, and the app version and build so Support can take a closer look.
