App no longer stays open in taskbar; automations don't run

Microsoft Store version on Windows 11; can't find a version number.

When I first got the beta version, I noticed Codex would show up as an icon in my taskbar and allow me to close the window while keeping it running. That is no longer the case, and everywhere I've looked for config to change that has turned up nothing.

Was this feature nixed? I set up an automation to run in the wee hours, but opened the interface this morning to find it hadn't done anything.
