How to debug ChatGPT app widget in ChatGPT Android App

Hi @amoywolf I’d avoid relying on window.openai.userAgent unless OpenAI documents it as a stable contract. I’m not seeing an official Apps/ChatKit doc that guarantees that property, so capability detection is the safer path than UA sniffing. For debugging, I’d separate: widget logic — reproduce first in browser / standard ChatKit flow host-specific behavior — then compare against the app surface Official starting points: ChatKit overview: https://platform.openai.com/docs/guides/chatkit⁠ ChatKit widgets: https://platform.openai.com/docs/guides/chatkit-widgets⁠ Advanced/custom ChatKit integrations: https://platform.openai.com/docs/guides/custom-chatkit⁠ So my rule would be: don’t depend on undocumented host detection, prefer feature checks, and isolate web-vs-app behavior with strong widget-side logging.
