Hi, I am currently on Paid Tier 1 and would like to upgrade to Tier 2.
- Total spending: ~$282 (₺11,300)
- First payment date: December 8, 2025 (90+ days ago)
I meet all the documented requirements ($250+ cumulative spend and 30+ days since first successful payment), but the Upgrade button does not appear on the API Keys page in Google AI Studio.
Could you please help me upgrade to Tier 2? Thank you.
