Billing sync issue: AI Studio shows Tier 1 - Prepay but no credits available

I have an active Google Cloud billing account with a balance of $10.

In Google AI Studio, my project status is Tier 1 - Prepay.

When trying to generate an image, you receive an “Insufficient credits” error.

The Settings → Plan information menu item is missing, so I can’t manage my subscription.

I’ve already contacted Google Cloud support, but they redirected me here.

i have the same issue in my google cloud console i have the cradits but in google ai studio is showing that you have 0 cradits in tier 1
