Manual billing sync request — Inactive or unsupported despite active billing account

Billing Account ID: 0150F9-D8F1CF-E5C4..

Project: Linkedin-Automation (gen-lang-client-08206410..)

Issue: AI Studio shows “The billing account type is inactive or unsupported” despite having an active Google Cloud billing account with $9.96 in prepaid credits. The Gemini API Billing page says “Free tier” and requires an active billing account to upgrade, but the billing account is already linked and funded.

Impact: Imagen 3/4 API calls fail with:
Imagen 3 is only available on paid plans. Please upgrade your account at https://ai.dev/projects.

Requesting a manual billing sync to move this project to Tier 1. Thank you.

Exact Error:

Imagen 4 failed (400):

“error”:

“code”: 400, “message”: “Imagen 3 is only available on paid plans. Please upgrade your account at https://ai.dev/projects.”, “status”: “INVALID_ARGUMENT”
