Request to review account flag: Billing Tier shows Unavailable (403 PERMISSION_DENIED)

Hi Google AI Team,

My project/account seems to have been automatically flagged. In Google AI Studio, my projects are showing “Billing Tier: Unavailable”, and API requests consistently fail with:
“403 PERMISSION_DENIED: Your project has been denied access. Please contact support.”

I have verified all the following requirements on my Google account:

  1. Date of Birth is verified and confirms I am an adult (over 18).
  2. Phone number is added and 2-Step Verification (2SV / MFA) has been successfully enabled.
  3. The project is created under Google Cloud Console.

Account Email: y…@gmail.com
Project ID: gemini-cli-dev-50940..

I am an individual developer using this for personal learning and testing with Gemini CLI. Could you please help review and remove the flag so I can access the free tier?

Thank you for your assistance!
