Entitlement Bug: Nano Banana 2 asking for upgrade in AI Studio on Google AI Ultra account

Hi everyone,

I am experiencing a weird account entitlement / billing sync issue in Google AI Studio.

The Issue:
When I try to use Nano Banana 2 in the AI Studio Playground on my Google account, it keeps asking me to upgrade, even though I have an active Google AI Ultra subscription.

Context & Troubleshooting Done:

  • Cross-account check: I have another Google account with AI Pro where Nano Banana 2 works perfectly fine inside AI Studio without any issues. So I would assume that the Ultra would be even better, but it doesnt work. Both accounts are personal and I cannot see any difference in the settings.

  • Project settings: I have verified that I am using the default personal project space, not an external GCP project.

  • Browser troubleshooting: I have tried logging out completely, clearing my cache, and using an Incognito window, but the upgrade prompt persists on this specific account.

It seems like my account is stuck in a backend loop where AI Studio fails to recognize my Google AI Ultra subscriber benefits and defaults to the restricted free tier instead.

Could a support agent or engineer please look into my account provisioning and force a sync on the backend?

Thank you!
