Manual billing sync request — "Set up prepay" blank screen bug despite funded Cloud account

Hello,

I recently upgraded my project to the Paid Tier and successfully loaded a manual payment of ₹1,000 into my Google Cloud Billing account. However, my Google AI Studio dashboard is still showing my project as “Tier 1 · Postpay” and is prompting me with a “Set up prepay” link.

When I click “Set up prepay”, the iframe fails to render and only displays a blank black box. I have tested this across multiple browsers (Chrome, Edge) and Incognito modes with no success, which appears to be a known syncing issue.

Could a staff member please perform a manual billing sync for my account so my project can recognize my prepaid credits and access the paid tier limits?

Project ID: gen-lang-client-05734804..

Thank you!
