Billing Sync Issue: AI Studio shows "No available credits" despite having $300 GCP Free Credit

Hi Google AI Team,
I am experiencing the known billing sync issue between Google Cloud Billing and Google AI Studio.
My GCP Billing Account is active and has a $300 Free Trial Credit available. However, my project in AI Studio (Tier 1 - Prepay) is stuck on the “Action needed: No available credits” warning, and my API key is returning a 429 error.

My details:

  • Billing Account ID: 014582-982D20-EC…

  • Project ID: gen-lang-client-0593632…

Could an engineer please manually sync my account to recognize the credits? I have attached screenshots of my GCP billing page and the AI Studio error. Thank you!
