Tier 2 upgrade button not showing — $267 spent, 38 days since first payment

Hi, I meet all Tier 2 requirements but the upgrade option is not available in the UI. Project: Nano Banana Current tier: Paid Tier 1 Cumulative spend: $267+ API key created: Jan 27, 2026 (38 days ago) The three-dot menu on the API Keys page only shows “Rename key” and “Delete key” — no upgrade option anywhere. Please help with the Tier 2 upgrade. Thanks.
