Apps SDK: multiple widgets in a single chat turn fail to render inside the native ChatGPT mobile app

I’ve been developing an app for ChatGPT with Apps SDK and sometimes the agent decides to perform multiple tool calls that each can render its widget in a single chat turn. Why this might not be the most common use case for most apps, it’s a completely justified use case for my app. This works OK on the web (both desktop and mobile), but fails quite randomly inside the native mobile app. Expected behavior: * Multiple widgets are correctly rendered. Actual behavior: * 1 o 2 widgets are rendered, rest are not for no reason at all (no Sentry errors, widget code is directly not being initialized)
