New AMAPI project blocked by "organization reached its usage limits" during device enrollment

Hi there,

I'm a new developer building an EMM solution (Xentrio, by MGProTech Inc.) on the Android Management API, currently in early integration/testing.

Environment:
- New Google Cloud project: xentrio-android-mdm
- Android Management API enabled, billing active
- New service account created with Android Management User role
- New Android Enterprise created via signupUrls/enterprises.create (Gmail-based, not Workspace)
- Policy created successfully (policy1)
- Enrollment token and QR code generated successfully with no errors

Issue:
When scanning the enrollment QR code on a physical test device (Samsung Galaxy A10e, Android 11), provisioning fails immediately with:

"Can't set up device. Since your organization reached its usage limits, this device can't be set up."

The device never appears in the Android Management API device list — inventory remains empty. I have zero enrolled devices currently, so this appears to be the known default "Safety Quota" of zero applied to new/unverified projects rather than an actual usage limit being hit.

I don't see this quota exposed under IAM & Admin > Quotas (Android Management API only shows requests-per-minute quotas there), nor under "Increase Requests."

Could someone from the team help lift or increase the device enrollment quota for this project? Happy to provide any additional details needed.

Project ID: xentrio-android-mdm
Enterprise: enterprises/LC00n0hupg

Thanks!
