What version of the Codex App are you using (From “About Codex” dialog)?
260208.1016 (571)
What subscription do you have?
Business
What issue are you seeing?
When starting the Codex app it is very slow and typing in the prompt is not possible. After a short while it becomes entirely unresponsive and is completely unusable. It was working last week so a recent update may have broken it.
M1 Macbook Pro
macOS Tahoe 26.1 (25B78)
What steps can reproduce the bug?
Start the app and it is unusable.
What is the expected behavior?
It should be responsive and accept input.

'At Startup' is superfluous. This app is unusable.
We've fixed a bunch of perf issues in the past week. Are you still seeing this problem with the latest version?
I had switched to an alternative but I've just tried it again and it's working fine for me now. Thanks for working on it.
