Web: Switching to GPT‑5.5 Pro redirects to GPT‑5.3 mini

Hi everyone, I’m experiencing a frustrating issue with the ChatGPT web version. Whenever I select GPT‑5.5 Pro from the model picker, the system silently routes me to GPT‑5.3 mini instead. This happens consistently, and I can’t seem to force the Pro version to load. Is this a known bug, or am I doing something wrong? I’ve already tried clearing cache, reinstalling the app, and switching networks – no luck. If anyone has a workaround, or if an OpenAI staff member could clarify whether this is intended (maybe a load‑balancing fallback?), I’d really appreciate it. This is blocking my design work, and I’d love to get it resolved soon. Thanks in advance for any help!
