Hi, i'm on codex pro plan and it silently routes to 5.2 today, WTF? Anyone else gets similar behaviour? I was working with it since morning (UTC) and afternoon sudenly it became much slower and got very different feeling, so I started digging and enabled codex logs and got:

it's back today, even I'm verified on https://chatgpt.com/cyber, fortunately I can notice pretty quickly when it happens now - difference is apparent
