Project stuck on Tier 1 although both Tier 2 criteria are clearly met:
- Project ID: aerial-sandbox-315310
- Billing account: 01E070-5FCF5E-953305
- Gemini API spend (AI Studio Spend page, "only Gemini API usage"): ~$4.13K
over the last 90 days — far exceeding the $100 threshold
- First billing: 2026-05-15 (3+ weeks ago, well past the 3-day requirement)
- Status: still Tier 1 · Postpay
The billing page states the upgrade is automatic once criteria are met, but it
hasn't applied. Please check and manually apply the Tier 2 upgrade.
