No Usage sessions showing up

• Consent — consent must be exactly true after your CMP grants analytics. Anything else = no capture.
• Site key — must match the project’s current key.
• Credits — shared wallet empty, or this project’s reservation is empty and unallocated is also empty.
• Sample rate / path allowlist — Project → Usage → Capture settings. Allowlist limits which paths start a session.
• Ad blockers — rare, but can block the script host.

Smoke-test on your app origin with /usage-smoke.html when signed in as that project’s owner.
