Google AI Pro users stuck on Antigravity Starter quota despite active subs

If you pay for Google AI Pro and expect Antigravity to hand you the premium rate limits immediately, you might be staring at the wrong dashboard. The entitlement check is failing for several subscribers, locking them into the "Starter Quota" even when their Google accounts show active status. This isn't just a UI glitch; it prevents access to the higher throughput tiers that justify the subscription cost. The bug specifically triggers when the app reports, "This account is ineligible for higher rate limits through a Google AI plan at this time," regardless of payment status.

Why the Pro entitlement gets lost

The core issue usually stems from how the subscription was purchased or how the Google account data syncs with Antigravity's backend. Many users buy the subscription via third-party stores, most notably Apple’s App Store. While the payment goes through and the Google account registers the feature, the handshake between the store receipt and Antigravity’s API can drop the signal.
You might have an active subscription on the Google account linked to the app, but Antigravity still displays the generic plan tag. The error message explicitly states your plan is "Antigravity Starter Quota." Even after completing mandatory age verification, the quota doesn't update. Signing out and signing back in rarely forces a fresh token check, leaving the account stuck in the lower tier.

Diagnosing the mismatch

Before assuming your subscription lapsed, verify the chain of custody for your Pro status. If you subscribed via the Apple App Store, the confirmation email comes from Apple, but the entitlement lives in your Google profile. Antigravity pulls data directly from Google, not Apple. If there is a delay in Google propagating that status to the external app endpoints, Antigravity reads zero credits.
Check these specific signs of the bug:

• Display Text: Look for the exact string "Your Plan: Antigravity Starter Quota" in the settings menu.
• Eligibility Message: The app will show "This account is ineligible for higher rate limits through a Google AI plan at this time."
• Persistence: The state remains after force-quitting the app, clearing cache, or toggling Wi-Fi.

If you see both messages while knowing your Pro sub is active, the data sync has broken. Standard troubleshooting like re-installing the app often fails because the local credentials remain cached with the old state.

How to force a re-sync

Since standard logout steps don't trigger a backend refresh, you need to manually prompt Antigravity to re-query your Google account. The app includes a direct feedback channel that functions as a diagnostic trigger, not just a support ticket.

1. Open Antigravity and go to the settings or menu.
2. Select the "Provide Feedback" option.
3. Choose or generate an Auth and Billing report. This action captures your current session tokens and subscription metadata.
4. Submit the report. This does not guarantee an instant fix, but it flags the account for manual or automated re-validation by the developers.

Users reporting this issue note that even after submitting this report, the fix can take up to twenty-four hours. The backend might need to reconcile the Apple purchase receipt with the Google AI Pro license ID. If you bought directly through the Google Play Store or a web browser, this sync issue is less common, but still possible if multiple Google accounts are merged under one alias.

What to do while you wait

You cannot manually override the quota cap. Running large batches or image generation tasks while on the Starter tier will hit the rate limits quickly. If you rely on the Pro throughput, switch to a different model or task until the status updates. There is no command-line flag to force the quota upgrade; it depends entirely on the server-side recognition of your Pro license.
If the issue persists beyond a day after submitting the Auth report, gather proof of purchase. Screenshot your Google Play or Apple subscription status showing "Active" next to "Google AI Pro." Send this alongside a new feedback submission. The developers need to map the transaction ID to your Antigravity user profile manually if the automatic webhook fails.
This bug highlights the friction between third-party payment rails and service entitlement checks. Until the API call reliably returns the Pro status, you will remain capped. Verify your subscription source first, then use the internal feedback tool to reset the check. Avoid paying for duplicate services while waiting for the sync to complete.
