Gemini Pro quota stuck at 0% after reset – likely multi-account session bug (workaround included)

Google Antigravity
1

I’ve been experiencing a persistent issue with Gemini Pro quota not resetting correctly in Antigravity.

Problem:

  • After waiting for the quota reset (even up to 3+ weeks), Gemini Pro remains at 0% available quota

  • Other models (e.g. Flash) continue to work normally

  • The reset timer completes, but the quota is not restored

At first, this looked like a backend quota bug. However, after further testing, the issue appears to be related to multi-account sessions in the browser.

Key Finding:
When using a browser profile with multiple Google accounts logged in simultaneously, Antigravity seems to:

  • mix session tokens / cookies

  • read an incorrect or stale quota state

  • keep Gemini Pro stuck at 0%

Workaround (confirmed working):

  1. Use a clean browser profile (or incognito)

  2. Log in with only one Google account

  3. Access Antigravity

:white_check_mark: Result:

  • Quota resets correctly

  • Gemini Pro becomes usable again

  • No more “stuck at 0%” issue

Additional Notes:

  • Logging out is not always sufficient — browser profiles still retain session artifacts

  • The issue does NOT seem to affect all models equally (Pro is most impacted)

  • This suggests a problem with session handling + quota backend synchronization

Suggested Fix:

  • Ensure strict isolation of quota state per account (independent of shared browser sessions)

  • Avoid cross-account token contamination when multiple Google accounts are active

Conclusion:
This is likely not a pure quota reset bug, but a session management issue affecting quota resolution.

Until fixed, using a single-account browser profile is a reliable workaround.
