The phone number was used several years ago and is no longer in service or valid, unable to receive SMS and WhatsApp verification codes.
I have already registered for advanced account security, yet I am unable to log in to Codex.
I found a post titled Codex client auth forces WhatsApp code to a dead number — but ChatGPT/Codex web log in fine (Case 09491223) - #14 by owallesun ，but I don’t know the current progress, and I’m unsure what to do now. This issue has been bothering me for several days.
