Incompatibility or Security preventing UI rendering and Calling API

Gemini API

​"I am reporting a critical failure in the code preview/collaborative app feature on my Pixel mobile phone.

  1. ​Rendering Crash: Every single-file web application (React, HTML/JS) created in the chat results in an immediate white screen upon clicking ‘Preview.’ The app fails to load the UI entirely.

  2. ​API Blocking: When I ran the app externally, the Text-to-Speech (TTS) feature failed with a modal error: ‘Failed to generate audio. The API may be unavailable or blocked.’ (Error screenshot attached/referenced).

​This suggests a severe incompatibility or security restriction within the mobile Gemini interface is blocking both UI rendering and necessary API calls."
