The voice transcription button has disappeared in the MacOS Codex app!

Thanks for clarification. The voice input should still be there, at least, I couldn’t find any evidence stating otherwise. Can I hear out that in a previous version the voice input worked flawlessly?

I guess the feature is still not that stable for everyone. Did you already try the shortcut (Ctrl + M) out? Or did you try to restart the app immediately after granting permission?
