Can’t access higher usage tier in AI Studio despite spending over $250 and first payment over a month ago

Hi everyone,

We’ve been actively using the Google AI Studio (Gemini API) for over a month now. Our total spend on Google Cloud has already exceeded $250 USD, and our first payment was processed more than a month ago.

However, I still don’t see any option to upgrade our API key usage tier in the AI Studio dashboard. We need to move to Tier 2 or higher to support production workloads (we’re generating AI-based podcasts for thousands of students, and the current Tier 1 rate limits are blocking functionality).

Could someone from Google confirm how long it typically takes for the upgrade option to appear, or if there’s an additional step we need to complete (e.g. verification, billing setup, or form submission)?

Any help or clarification would be greatly appreciated — this is currently blocking a live production feature.
