Prepaid balance showing $0.19 in AI Studio despite $20.96 unspent adjustment in Cloud Billing Ledger

Hi everyone,

I am experiencing the known AI Studio prepaid balance synchronization bug. On Saturday (Sept 5), I made a manual prepayment of US$25.00 to transition to Tier 1.

After a local VAT deduction of US$4.04, my net funding amount was US$20.96. My Google Cloud Billing Cost Table correctly reflects this as an unspent credit under “Adjustments (US$20.96)” with zero project-level infrastructure or API usage charges. My Postpay history is completely empty.

However, the Gemini API / AI Studio interface is failing to read this pool. It shows an ending balance of US$0.19, falsely triggering credit depletion errors when I try to make simple requests using the Gemini 2.5 Flash-Lite model.

  • Billing Account ID: 01E8F8-632F23-E2…
  • Invoice Number: 56867001..
  • Transaction Date: 2026-09-05

Could a community manager or Google support representative please request a manual balance synchronization for my AI Studio prepay bucket?
(Note: I am attaching screenshots of my Prepay Ledger and Cost Table for verification.)
