[Bug/Quota] AI Pro Subscription Fails to Sync in Antigravity IDE (Stuck on Free Tier)

Issue Summary: My Google account has an active AI Pro subscription, but the Antigravity IDE is failing to sync this entitlement. The IDE is currently treating my account as a Free/Individual tier and locking me behind the weekly quota limits instead of the 5-hour Pro refresh cycle.

Expected Behavior: The IDE should recognize the active AI Pro subscription upon login and apply the Pro quota limits (refreshing every 5 hours).

Actual Behavior: The IDE enforces the Free tier weekly quota. While my Google account billing and the web interface acknowledge my Pro status, the Antigravity IDE does not reflect this.

Troubleshooting Steps I Have Already Taken: To rule out local configuration issues, I have already completed the following workarounds without success:

  • Signed completely out of the IDE and re-authenticated using a clean, isolated browser profile with only the subscribed Google account logged in (to prevent profile mismatch).

  • Performed a clean reinstall of the Antigravity desktop app and deleted local application data folders.

  • Started fresh without importing any previous settings.json files to avoid the known JSON parsing bugs.

  • Checked my Google Account security settings to ensure no rogue third-party extensions are silently draining my background quota.

Because the local fixes did not resolve the issue, it appears my account is stuck in a backend database desync loop. I am requesting a manual entitlement re-sync for my account.

Environment Details:

  • Operating System: Windows 11

  • Antigravity Version: Antigravity Version: 1.20.5

  • Default Browser Used for Login: Chrome
