Same here, happens twice a day. SUPER annoying and breaks the prod. I filled a ticket and waited for 3 days to get a “All good, we can see you’re on tier 3 now” just before another downgrade to tier 1.
We are seeing the same recurring production incident today (Aug 24, 2026) on billing account 01F46F-…-684278.
Google repeatedly sent automatic emails confirming Paid Tier 3 on Aug 8, 11, 16, 20, 23 and 24. The latest email says Tier 3 limits and the higher spending cap are already active, yet AI Studio still shows Paid Tier 1 with a EUR 219.45 billing account tier cap. Current August Gemini spend is about EUR 471.56, so the retroactive Tier 1 cap immediately pauses service.
Payments are healthy: Postpay active and a EUR 500 payment succeeded on Aug 19. The issue affects two production projects, VlogMe PROD and Aisma, and causes user-facing outages.
We submitted the official Gemini API Tier Downgrade Report today and opened a live Google Cloud Billing Support escalation. Please add this billing account to the engineering investigation and provide a permanent fix/RCA. The repeated Tier 3 confirmation emails while the enforcement system remains on Tier 1 strongly suggest a backend tier synchronization failure.
