Account ineligible on a previously working personal Gmail despite supported region and completed age verification

Hello,

I’m seeing an “Account ineligible” error in Google Antigravity on a personal Gmail account.

What I verified:

- This is a personal Gmail account, not a Workspace account.

- Fresh Google sign-in succeeds successfully.

- The country shown on the Google Terms page is South Korea.

- The Google age verification page shows that age verification is already completed.

- The same account worked with Antigravity as recently as May 22, 2026.

- Starting on May 23, 2026, Antigravity immediately returns:

“Account ineligible: Your current account is not eligible for Antigravity. Verify your account to continue.”

This appears to be account-specific rather than a local machine, browser, or network issue.

Could someone please check:

1. whether the account has lost Antigravity entitlement,

2. whether there is any policy or trust/enforcement flag on the account,

3. whether this is a backend eligibility bug that can be cleared manually?

If there is a specific remediation step required, please let me know exactly what to do.

Thanks.
