[URGENT] Billing Sync Issues: Project downgraded to Tier 1 (Active Billing / 429 Errors)

Hello Google AI Team,

My projects have been unexpectedly downgraded to Tier 1, causing immediate production disruptions with 429 RESOURCE_EXHAUSTED errors.

Project Details:

  • Project ID: gen-lang-client-0022053381

  • Error Message: 429 RESOURCE_EXHAUSTED: "Your prepayment credits are depleted. Please go to AI Studio to manage your project and billing."

  • Previous Tier: Tier 2

Context & Payment History:

  • Active Billing: My Google Cloud Billing account is active, and has an established payment history.

  • Recent Payments: I paid approximately $150 USD for Gemini API usage last month and have no outstanding balances or pending payments.

  • Current Issue: Despite my payment history and active credits, Google AI Studio is reporting my prepay balance as $0.00 and has downgraded my project to Tier 1 limits.

  • Attempted Fixes: I recently change my API keys to other project that still got tier 2, but the issue persists across all existing projects in the same billing. I ask Gemini about this, and Gemini suggest that this appears to be the widespread billing/prepay synchronization bug currently being reported by other users.

Request: Please help us to resolve this issues, since we cannot use and activate GEMINI API KEY for our projects.

Thank you for your help..

Best Regards,
BC
