Hey Google team,
I’ve been facing a critical issue with the Web Search / Grounding feature for the past 2 days.
Here are the exact details:
* **Gemini 3.1 Pro:** Search/Grounding is completely broken. It returns no grounding results at all, and the metadata shows empty search queries.
* **Gemini 3 Flash:** Web search is working perfectly fine.
* **Scope:** I have reproduced this across multiple Google accounts, confirming it is a model-side issue. It is also occasionally happening via the API.
This is causing major disruptions to my application. Please prioritize a fix for the Gemini 3.1 Pro search tool.
Thanks.
