I’m seeing an inconsistency between Gemini API billing status and quota tier in Google AI Studio.

### Current Situation

Billing page shows:

- Billing account active

- Status: **Paid 2**

- Billing account linked correctly

- Active production workload

But the Usage page still shows:

- **Tier 1**

- Tier 1 rate limits/quota behavior

- Persistent `429 TooManyRequests`

Environment:

- Gemini API via AI Studio

- Production OCR / document digitization pipeline

- High-volume parallel processing workload

### Symptoms

- Heavy 429 spikes despite billing being enabled

- Usage page explicitly says “Tier 1”

- Billing page says “Paid 2”

- API behavior still matches Tier 1 quotas

### What I’ve Already Checked

- Billing account is active and valid

- API keys are using the billed project

- Requests are being billed

- Spend/usage graphs are updating correctly

- Multiple Gemini models are in use

### Questions

1. Is “Paid 2” different from actual quota/rate-limit tier?

2. Is there a propagation delay between billing activation and quota upgrade?

3. Does Gemini API require a minimum amount of _actual billed spend_ before quota tier changes?

4. Can quota upgrades be manually reviewed for production workloads?

5. Is this a known issue? I found similar reports from other users.

### Additional Context

This workload is hitting production throttling due to 429s, so clarification or a quota review would really help.

Would appreciate guidance from the Google AI Studio / Gemini API team.
