Error during billing setup after successful payment — prepay stuck on "Free trial" tier

Hi team,

I successfully added ₹1,000 (INR) as Prepay credit to my billing account on Aug 13, 2026. The transaction shows up correctly under Billing > Transactions, and “Prepay” is listed as my payment method.

However, my project’s Billing Tier still shows “Free trial” on the API Keys page. When I click “Activate billing” to upgrade, I get:

“Error during billing setup”

No further detail is shown.

Details:

  • Project: Gemini Project
  • Project ID: gen-lang-client-06596856..
  • Billing account ID: 016062-CAEAAA-F83C..
  • Payment: ₹1,000 added Aug 13, 2026, via Prepay/UPI
  • India tax info: already submitted (was flagged as required, I completed it)

I’m building a real education app that needs the paid tier’s higher rate limits — the free tier’s rate limit is blocking real usage. Could someone please check if my billing account needs a manual sync? Happy to share screenshots with you.

Thank you!
