This may be relevant: OpenAI removed GPT-5.3 Codex from the ChatGPT plans in June. The model is now only available via the API – but it appears to be the ‘default’ model in the Codex settings for the XCode Agents. With other models such as GPT-5.4, GPT-5.4-Mini and GPT-5.5 (depending on what’s available in your GPT account), agent mode should work in a new Codex session. BTW: Is it just me, or is there no UI to set the reasoning level for the agents? ...

Is there any news or workarounds for this? I run into the same problem using iOS 18.2 (SDK Build 22C148) on a device (but not in the simulator): The navigation title covers the content of the list after a ‘scroll to top’ triggered by a tap on the active tab. FB16171220
