Google AI Pro account stuck at "Further action is required" in Antigravity IDE

My Google account has an active Google AI Pro subscription.
Browser authentication completes successfully, but Antigravity IDE
continues to show:

“Further action is required to use Antigravity.
Please verify your account, then sign in again to continue.”

I have already completed account verification and tried signing out,
removing Antigravity OAuth access, resetting onboarding, and clearing
the local configuration.

Could you please check whether my account’s Antigravity eligibility
or entitlement status is incorrectly flagged?

Hi @Christina_Kay,

Welcome to the Forum,

Could you please confirm If your 2-Step Verification is configured and that there are no pending security alerts on your account?

Additionally, if you are using a VPN or specific network routing, try disabling it temporarily to see if the authentication completes successfully, as network-level risk flags can sometimes trigger this loop.
