Why did Codex stop sharing to Facebook?

Hi and welcome to the community! Is there a specific reason why you think Codex is at fault here? For example, from experience, Meta/Facebook appears to block some third-party AI services on its platform. One example is that 1-800-ChatGPT is no longer available through WhatsApp. > Unfortunately, due to a policy and terms change from WhatsApp, ChatGPT will no longer be available on WhatsApp after January 15, 2026.
